Arthur H. Healey, J.
On February 12, 1977, a fire broke out in a building located on Highland Avenue in Waterbury. The building was owned by Louis Cipriano and was under a lease to the defendant for his exclusive use as a pizza restaurant. The premises suffered extensive damages rendering them unfit for occupancy. In an information filed [230]*230in April, 1977, the defendant was accused of starting this fire and was charged with arson in the second degree in violation of General Statutes § 53a-112.1
On June 21, 1977, the defendant filed a motion to suppress all evidence, and related testimony, obtained in a search of the premises by police and fire officers on February 23, 1977. As the basis for his motion, the defendant claimed that the search was conducted without a warrant and without his consent. After an evidentiary hearing on the matter, the court, Maiocco, J., granted the defendant’s motion. Thereafter, the defendant filed a motion to dismiss the information against him with prejudice which was granted by the court, Henebry, J., on November 12, 1980. On the same day, the state filed a request, pursuant to General Statutes § 54-96, for permission to appeal the judgment, which was granted by the court.
To assess the parties’ claims properly, it is necessary to delineate certain events that led to the search of the leased premises on February 23, 1977, and to examine the business relationship between the defendant and his landlord, Cipriano, as that relationship was affected by the events occurring between the time of the fire and the search. The defendant was assigned the lease for the premises on April 15, 1976, with a term that ran until October 31, 1978. The defendant was current in [231]*231his rent through the month of February, 1977. Furthermore, the court found that the lease had not been terminated at the time the officers conducted the warrantless search.
There are four clauses in the lease that are relevant to this appeal. The third clause provides, in part, that “if the leased premises shall be deserted or vacated, the Landlord or its agents shall have the right to and may enter the said premises as the agent of the Tenant.” The tenth clause gives the landlord the right to enter the premises at reasonable hours to inspect and to make any necessary repairs on the premises. The eleventh clause deals with the parties’ rights in the event the premises were destroyed by fire, explosion or otherwise. It provides as follows: “In the event of the destruction of the demised premises or the building containing the said premises by fire, explosion, the elements or otherwise during the term hereby created, or previous thereto, or such partial destruction thereof as to render the premises wholly untenantable or unfit for occupancy, or should the demised premises be so badly injured that the same cannot be repaired within ninety days from the happening of such injury, then and in such case the term hereby created shall, at the option of the Landlord, cease and become null and void from the date of such damage or destruction and the Tenant shall immediately surrender said premises and all the Tenant’s interest therein to the Landlord, and shall pay rent only to the time of such surrender, in which event the Landlord may re-enter and re-possess the premises thus discharged from this lease and may remove all parties therefrom. Should the demised premises be rendered untenantable and unfit for occupancy, but yet be repairable [232]*232within ninety days from the happening of said injury, the Landlord may enter and repair the same with reasonable speed, and the rent shall not accrue after said injury or while repairs are being made, but shall recommence immediately after said repairs shall be completed. But if the premises shall be so slightly injured as not to be rendered untenantable and unfit for occupancy, then the Landlord agrees to repair the same with reasonable promptness and in that case the rent accrued and accruing shall not cease or determine. The Tenant shall immediately notify the Landlord in case of fire or other damage to the premises.” Finally, the twenty-fourth clause provides that “[t]he foregoing rights and remedies are not intended to be exclusive but as additional to all the rights and remedies the Landlord would otherwise have by law.” The significance of these clauses will be addressed while examining the substantive issues raised by this appeal.
As previously noted, the fire occurred on February 12,1977. The defendant testified at the hearing on the motion to suppress that he first found out about the fire on Sunday, February 13, 1977, from both the landlord and his own daughter. He did not go into the restaurant on that day, but he did call the fire marshal to make an appointment for the marshal to inspect the premises the following day. Meanwhile, on Sunday, Cipriano had someone secure the building by boarding it up.2 [233]*233He also testified that he had a new door put on the side of the building.3 In response to a question asking him why he hadn’t replaced the door, the defendant stated: “I didn’t know that he had put the door and I didn’t know whether he wanted to throw me out.”
On Monday, February 14, two members of the Waterbury fire marshal’s office inspected the premises. There was conflicting testimony as to who let them in;4 however, it was the defendant who showed them around. Nothing was removed on that day, but the marshals were able to determine the place of origin of the fire.5 The defendant resecured the premises when they left. The defendant at one point testified that he did not tell them they could not reenter the building because “I can’t stop anyone.”
The defendant visited the premises on at least two other occasions. Between February 16 and February 18, he met a representative of his insurance company, and on February 22, he met an inspector from the Waterbury health department. The defendant was concerned with the restaurant goods and equipment6 that remained in the premises. After each visit, the defendant resecured the premises.
[234]*234The defendant and Cipriano were in the building together on two or three occasions. One of the occasions was when the defendant was with his insurance representative. The defendant asked Cipriano to leave because he was making too much noise. Cipriano thereupon left. On no other occasion did either the defendant or Cipriano ask the other to leave.7
No formal action was taken on the part of the defendant or Cipriano to terminate the lease in accordance with its terms in the event of a fire. While the defendant testified that he did not really understand the lease, he felt that the lease was broken by the fire but that he was entitled to stay in the premises until the end of February because his rent was paid. Cipriano, on the other hand, requested that the defendant pay the rent for March.8 Both Cipriano and the defendant cleaned out the premises. The defendant testified that although he felt that the lease was broken, it was also his responsibility to “repair” the place. He did not, however, take any action to make any substantial repairs because he was waiting for his insurance claim to be settled.
The search which was the basis for the defendant’s motion to suppress occurred on February 23, 1977, eleven days after the fire. Officers of the Waterbury police department, the Waterbury fire [235]*235department, and the state police department were granted access to the premises hy Cipriano. Neither a search warrant for the premises nor the permission of the defendant was sought by the officers. The police knew the defendant operated the restaurant and considered him to be a suspect. The sole purpose of the entry was to search for and obtain evidence of the arson. Upon gaining entry, the officers checked the air for hydrocarbons and removed a small piece of charred carpeting for testing. The rug was installed by Cipriano. In his motion, the defendant sought to suppress the test results on both pieces of evidence, as well as all evidence based upon the search of the premises and seizure of the evidence.
As a result of the fire Cipriano collected $21,000 from his insurance company for damage to the building. At the hearing in January, 1979, the defendant said that he had not collected any money on his insurance claim.9 Subsequent to the fire, the defendant never reoccupied the premises or reopened the premises. After remaining vacant for seven months, the building was sold by Cipriano.
In making its claim that the trial court erred in granting the motion to suppress, the state essentially argues (1) that the defendant had no reasonable expectation of privacy in the premises searched that was fatally offended by the search, and (2) that the landlord Cipriano clearly had the authority to consent to the entry and the search by the officers whether such authority be denominated [236]*236actual authority or apparent authority, thus requiring the conclusion that the search was “reasonable” under the fourth amendment.10
The issue of whether a “search” comes within the protection of the fourth amendment involves a twofold requirement under Katz v. United States, 389 U.S. 347, 88 S. Ct. 507, 19 L. Ed. 2d 576 (1967) (Harlan, J., concurring). The first is whether the person who is the focus of the inquiry has “exhibited an actual (subjective) expectation of privacy and, second . . . [whether] the expectation be one that society is prepared to recognize as ‘reasonable.’ ” Katz v. United States, supra, 361. Where it is established that law enforcement officials have encroached upon a defendant’s reasonable expectation of privacy, and the trial court explicitly found that this had in fact taken place, then the focus of inquiry should move to the “reasonableness” of the search. That is, where there was a warrant, was it accomplished pursuant to the warrant and where there is no warrant, was it justified and thus constitutional because it was within an exception to the warrant requirement? The state does not disagree that the United States Supreme Court has made it clear that “a search conducted without a warrant issued upon probable cause is ‘per se [237]*237unreasonable . . . subject only to a few specifically established and well-delineated exceptions.’ ” Schneckloth v. Bustamonte, 412 U.S. 218, 219, 93 S. Ct. 2041, 36 L. Ed. 2d 854 (1973), quoting Katz v. United States, supra, 357; Coolidge v. New Hampshire, 403 U.S. 443, 454-55, 91 S. Ct. 2022, 29 L. Ed. 2d 564, reh. denied, 404 U.S. 874, 92 S. Ct. 26, 30 L. Ed. 2d 120 (1971); see also Stoner v. California, 376 U.S. 483, 486, 84 S. Ct. 889, 11 L. Ed. 2d 856, reh. denied, 377 U.S. 940, 84 S. Ct. 1330, 12 L. Ed. 2d 303 (1964); State v. Tully, 166 Conn. 126, 133, 348 A.2d 603 (1974); People v. Adams, 53 N.Y.2d 1, 7, 422 N.E.2d 537 (1981).
Two recognized exceptions to the warrant requirement are where searches have been undertaken pursuant to (1) “exigent circumstances”;11 see, e.g., Mincey v. Arizona, 437 U.S. 385, 392-94, 98 S. Ct. 2408, 57 L. Ed. 2d 290 (1978); Terry v. Ohio, 392 U.S. 1, 25-26, 88 S. Ct. 1868, 20 L. Ed. 2d 889 (1968); State v. Runkles, 174 Conn. 405, 412, 389 A.2d 730, cert. denied, 439 U.S. 859, 99 S. Ct. 177, 58 L. Ed. 2d 168 (1978); and (2) consent. See, e.g., Davis v. United States, 328 U.S. 582, 593-94, 66 S. Ct. 1256, 90 L. Ed. 1453, reh. denied, 329 U.S. 824, 67 S. Ct. 107, 91 L. Ed. 700 (1946); Dotson v. Warden, 175 Conn. 614, 618, 402 A.2d 790 (1978). The exceptions “have been jealously and carefully drawn.” Jones v. United States, 357 U.S. 493, 499, 78 S. Ct. 1253, 2 L. Ed. 2d 1514 (1958); see State v. Krause, 163 Conn. 76, 80, 301 A.2d 234 (1972). The burden of proof is upon the state to show that an exception exists. Coolidge v. New Hampshire, supra, 455; see McDonald v. United States, 335 U.S. 451, 456, 69 S. Ct. 191, 98 L. Ed. 153 (1948); [238]*238Dotson v. Warden, supra, 618; People v. Reed, 393 Mich. 342, 362, 224 N.W.2d 867, cert. denied, 422 U.S. 1044, 95 S. Ct. 2660, 45 L. Ed. 2d 696 (1975). The Connecticut and United States constitutions “equally and conjointly prohibit unreasonable warrantless searches of private property. U.S. Const, amends. IV and XIV, § 1, Conn. Const, art. I, § 7.” Dotson v. Warden, supra.
Before we analyze the issues raised by this appeal, it should be recognized that our power to upset the findings of the trial court is limited. "We have stated our function here on many occasions. “On appeal, it is the function of this court to determine whether the decision of the trial court is clearly erroneous. See Practice Book, 1978, § 3060D. This involves a two part function: where the legal conclusions of the court are challenged, we must determine whether they are legally and logically correct and whether they find support in the facts set out in the memorandum of decision; where the factual basis of the court’s decision is challenged we must determine whether the facts set out in the memorandum of decision are supported by the evidence or whether, in light of the evidence and the pleadings in the whole record, those facts are clearly erroneous. That is the standard and scope of this court’s judicial review of decisions of the trial court. Beyond that, we will not go.” Pandolphe’s Auto Parts, Inc. v. Manchester, 181 Conn. 217, 221-22, 435 A.2d 24 (1980).
The appropriate starting point for fourth amendment analysis here is, thus, the defendant’s reasonable expectation of privacy. Katz recognized the importance of the individual’s expectations of privacy when it explained: “For the Fourth Amendment protects people, not places. What a person [239]*239knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection. [Citations omitted.] But what he seeks to preserve as private even in an area accessible to the public, may be constitutionally protected.” Katz v. United States, supra, 351-52. The requisites for judicial recognition of a reasonable expectation of privacy that are to be given fourth amendment protection are (1) that the person involved exhibit an actual (subjective) expectation of privacy, and (2) that the expectation was one to be recognized (by society) as “reasonable.” Katz v. United States, supra, 361. A reasonable expectation of privacy is one that is “legitimate.” See Rakas v. Illinois, 439 U.S. 128, 143, 99 S. Ct. 421, 58 L. Ed. 2d 387 (1978), reh. denied, 439 U.S. 1122, 99 S. Ct. 1035, 59 L. Ed. 2d 83 (1979); see also United States v. Salvucci, 448 U.S. 83, 91-92, 100 S. Ct. 2547, 65 L. Ed. 2d 619 (1980). Rakas also held that an illegal search only violates the rights of those who have “a legitimate expectation of privacy in the invaded place.” (Emphasis added.) Rakas v. Illinois, supra, 143. A person, of course, can have a legally sufficient interest in a place other than his own home so that the fourth amendment protects him from unreasonable governmental intrusion into that place. Jones v. United States, 362 U.S. 257, 263, 80 S. Ct. 725, 4 L. Ed. 2d 697 (1960); see Rakas v. Illinois, supra, 142-43. This also applies to commercial premises. See Marshall v. Barlow’s, Inc., 436 U.S. 307, 311-13, 98 S. Ct. 1816, 56 L. Ed. 2d 305 (1978); Camara v. Municipal Court, 387 U.S. 523, 534, 87 S. Ct. 1727, 18 L. Ed. 2d 930 (1967).
The determination of whether a person has exhibited a subjective expectation of privacy requires [240]*240a detached evaluation of the facts and circumstances of the particular case. See United States v. Brock, 667 F.2d 1311, 1320 n.8 (9th Cir. 1982); United States v. Sledge, 650 F.2d 1075, 1077 (9th Cir. 1981). As we have indicated, the trial court was presented with conflicting evidence at the hearing on the motion to suppress. It is the function of the trier to determine the credibility of witnesses and the weight to be given their testimony. State v. Rucker, 177 Conn. 370, 378, 418 A.2d 55 (1979); State v. Chisolm, 162 Conn. 631, 632, 295 A.2d 563 (1972). There was ample evidence to support the trial court’s determination that the defendant had a reasonable expectation of privacy “in the burned out and boarded up building” as of February 23, 1977. The court properly found, on this issue as well as on that of consent, that the defendant had not abandoned12 the leased premises. “Abandonment is a question of fact. ... It implies a voluntary and intentional renunciation, but the intent may be inferred as a fact from the surrounding circumstances. . . .” Pizzuto v. Newington, 174 Conn. 282, 285, 386 A.2d 238 (1978). On those occasions, between February 14 and February 23, when the defendant left the premises he secured them. He not only said that it was his intention to stay, but he always secured the site upon leaving because “I had my merchandise in there.” The defendant said that he had damaged personal property inside this building which he claimed was worth approximately $6750. He said he was keeping the premises because he intended to reopen the business and he wanted to “fix it so I could work.” No formal action was taken by either the defendant or the landlord to terminate the lease according to its terms in the [241]*241event of a fire. The landlord did not ask him to leave and turn the premises over to him. His rent was paid through the end of February and so he felt he had the right to remain there until at least that time “because of my rent paid.” He answered “yes” to the question: “Was it your intention to keep people out of the premises unless they were there with your premission?”13 There was thus evidence before the court that, if believed, actually demonstrated the defendant’s subjective expectation of privacy.14
Inasmuch as the trial court found that the defendant had a reasonable expectation of privacy, it follows that it also found that such an expectation in this case was one that “society is prepared to recognize as ‘reasonable’ ” under Katz and its progeny.15 [242]*242We agree that the court could legitimately conclude that this expectation was reasonable under the circumstances of this case. The court’s determination that the defendant had the requisite expectation of privacy is not clearly erroneous and must stand. See State v. Ostroski, 186 Conn. 287, 294, 440 A.2d 984 (1982); Pandolphe’s Auto Parts, Inc. v. Manchester, supra, 221-22; Practice Book § 3060D.
We turn now to the state’s claim that the court erred in finding that the defendant’s landlord, [243]*243Cipriano, did not have the right to consent to the warrantless search of the leased premises. “In Schneckloth v. Bustamonte, 412 U.S. 218 [93 S. Ct. 2041, 36 L. Ed. 2d 854] (1973), the Court reaffirmed the principle that the search of property, without warrant and without probable cause, but with proper consent voluntarily given, is valid under the Fourth Amendment.” United States v. Matlock, 415 U.S. 164, 165-66, 94 S. Ct. 988, 39 L. Ed. 2d 242 (1974). The general rule of law is that a landlord may not consent to a search of the tenant’s premises and this is true even where the landlord has some right to enter for purposes of inspecting and cleaning. Chapman v. United States, 365 U.S. 610, 616-17, 81 S. Ct. 776, 5 L. Ed. 2d 828 (1961). Professor LaFave, in stating that the general rule is that a lessor cannot give consent to a warrantless search of the premises occupied by his tenant, says: “The rule is not otherwise merely because the lessor has by express agreement or by implication reserved the right to enter for some special and limited purpose.” 2 LaFave, Search and Seizure § 8.5(a), p. 739.16 The state has the burden of proof on the issue of consent and that burden is not discharged by showing no more than acquiescence to a claim of lawful authority. Bumper v. North Carolina, 391 U.S. 543, 548-49, 88 S. Ct. 1788, 20 L. Ed. 2d 797 (1968); see United States v. Mendenhall, 446 U.S. 544, 557, 100 S. Ct. 1870, 64 L. Ed. 2d 497, reh. denied, 448 U.S. 908, 100 S. Ct. 3051, 65 L. Ed. [244]*2442d 1138 (1980). Consent is a question of fact to be evaluated under the totality of all the circumstances. Schneckloth v. Bustamonte, supra, 227; Dotson v. Warden, supra, 619. As a question of fact, it is to be decided by the trial court on the evidence it deems credible together with the reasonable inferences to be drawn from that evidence and its conclusions will stand unless they are clearly erroneous. Id.
The state recognizes that if it is found that the defendant had a reasonable expectation of privacy, it must prove that the consenting party “possessed common authority over or other sufficient relationship to the premises or effects sought to be inspected.”17 United States v. Matlock, supra, 171; Dotson v. Warden, supra, 621. The state maintains in its brief that, by operation of the lease and the fact of the fire, the landlord had “a right to possession superior to that of the lessee.” This claim goes as follows: construing the facts most favorably to the defendant the premises were untenantable but repairable within ninety days thereby implicating that portion of the lease (article eleventh)18 which provides: “ [T]he Landlord may enter and repair the same with reasonable speed, and the rent shall not accrue after said injury or while [245]*245repairs are being made, but shall recommence immediately after said repairs shall be completed.” The state’s claim continues, arguing that “obviously” the defendant was no longer in “exclusive possession”19 after the fire and he was not required to pay rent. Under the lease, the landlord was given, it continues, “an absolute right to temporary possession to perform certain activities” such as “the necessity to gut the premises to make necessary repairs . . . [the] need to bring in workmen, subcontractors, etc. ...” Asserting that the “landlord’s interest and peculiar relationship with the object of the search was obvious and unique,” the state submits that this was not a “general exploration of the premises” of a tenant such as is generally condemned; but rather it was for an air sample and the removal of charred rug for the “limited purpose of determining the cause of the fire which had recently done so much damage to his property.” Therefore, the state contends that “[h]is consent to the entry of those public officials charged with determining the cause of fires would appear to be the most reasonable and appropriate course of action in light of all the circumstances and the leases.”20
[246]*246The defendant argues that this warrantless search of his nonabandoned leased business premises eleven days after the fire was extinguished violates his fourth amendment protection against, unreasonable searches and seizures. He also argues that this search, which was for evidence of a crime, does not fall within any exception to the warrant requirement of the fourth amendment and especially that recognized where a proper third party may give a valid consent to search.
“While property ownership is clearly a factor to be considered in determining whether an individual’s Fourth Amendment rights have been violated . . , property rights are neither the beginning nor the end of [this court’s] inquiry.” United States v. Salvucci, 448 U.S. 83, 91, 100 S. Ct. 2547, 65 L. Ed. 2d 619 (1980). “The test applicable to third-party consent requires the state to prove that the consenting party ‘possessed common authority over or other sufficient relationship to the premises or effects sought to be inspected.’ United States v. Matlock, 415 U.S. 164, 171, 94 S. Ct. 988, 39 L. Ed. 2d 242 (1974). Matlock (p. 171) goes on to elaborate in a footnote on what constitutes ‘common authority.’ ‘Common authority is, of course, not to be implied from the mere property interest a third party has in the property. The authority which justifies the third-party consent does not rest upon the law of property, with its attendant his[247]*247torical and legal refinements,21 see Chapman v. United States, 365 U.S. 610 [81 S. Ct. 776, 5 L. Ed. 2d 828] (1961) (landlord could not validly consent to the search of a house he had rented to a another), Stoner v. California, 376 U.S. 483 [84 S. Ct. 889, 11 L. Ed. 2d 856, reh. denied, 377 U.S. 940, 84 S. Ct. 1330, 12 L. Ed. 2d 303] (1964) (night hotel clerk could not validly consent to search of customer’s room) but rests rather on mutual use of the property by persons generally having joint access or control for most purposes, so that it is reasonable to recognize that any of the co-inhabitants has the right to permit the inspection in his own right and that the others have assumed the risk that one of their number might permit the common area to be searched.’ ” (Emphasis in original.) Dotson v. Warden, supra, 622. Adopting a functional approach to this fourth amendment issue, the consent exception reflects a fair accommodation between constitutional requirements and the encouragement of effective law enforcement with the resolution to be made under the facts and circumstances of each case.
To begin with, the landlord clearly did not, as the state asserts, have, under the facts and the lease, a “superior” right of possession.22 The trial court made no finding that the premises were unten-antable and repairable within or without a ninety day period.23 The landlord did not repair the prem[248]*248ises within ninety days. The defendant and he both cleaned them. Although the rent was paid through February, the landlord, in contradiction to the lease provision upon which the state relies, not only demanded the rent for March but never pursued his option to “repair” by February 23. The landlord never asked the defendant to surrender the premises. Thus, in the circumstances of this case in ending the lease, the landlord’s right to possession was hardly “superior” to that of the defendant.
A fair reading of the trial court’s memorandum discloses that it concluded that the landlord’s consent on either the “common authority” or “other sufficient relationship” criteria of Matlock had not been proven by the state. We agree. The landlord took no action to terminate the defendant’s possession under the lease; he permitted the defendant’s property to remain and demanded another month’s rent. He did not demonstrate that he curtailed the defendant’s access; he even left the leased premises upon the defendant’s asking him to do so several days prior to February 23.24 It is true that the landlord caused the premises to be boarded up initially and entered the premises on several occasions after the fire. There was, however, no evidence that he exercised his “absolute right to temporary possession” as the state suggests concerning “the necessity to gut the premises to make necessary repairs and the corollary need to bring in [249]*249workmen, sub-contractors, etc . . . .”25 The defendant had not abandoned his possession. In addition, the court properly found that any right to inspect under the lease26 could not be enlarged here to authorize consent to officers to enter to gather evidence of a crime by the defendant. 2 LaFave, Search and Seizure § 8.5(a), p. 739; see Chapman v. United States, supra, 616; State v. Hodges, 287 N.W.2d 413 (Minn. 1980).27
The defendant was not contacted concerning giving any consent to this search. He lived in Waterbury and the police and fire officials involved knew he was there. He had not fled nor is it claimed he was likely to do so and this was eleven days after the fire. See Chapman v. United States, supra, 615. Only one day prior to the search, the landlord had seen the defendant when the latter had brought a check for property taxes to the landlord’s home. The landlord knew his consent was [250]*250not for a mere civil or administrative search, but for evidence of a crime; he said “they wanted to take evidence.” It is true that a “co-owner” has been said to have the authority to permit the search of a jointly held possession. Frazier v. Cupp, 394 U.S. 731, 740, 89 S. Ct. 1420, 22 L. Ed. 2d 684 (1969); Jackson v. Official Representatives & Employees of Los Angeles Police Department, 487 F.2d 885, 886 (9th Cir. 1973). This case, however, is not one of co-ownership. Nor is it one of joint or mutual use of that quality that pushes fourth amendment protections into the exception of consent.28
The state next argues that even if the landlord had no actual authority to consent, the search was [251]*251still reasonable under the fourth amendment because there was “apparent authority” for the search. It goes on to claim that, in measuring the facts of this case against the apparent authority doctrine, one must conclude that the officers acted in the “reasonable and good faith belief” that consent had been obtained from the proper party.29
The defendant claims that the record does not contain facts sufficient to justify the search on the doctrine of “apparent authority” which, in turn, would be necessary to support the state’s claim that the officers’ action based on that authority establishes a reasonable good faith belief by them that validates the search.
In pressing its line of argument the state points to the following circumstances: Cipriano owned the building, the premises had been “gutted” by fire, he (and not the defendant) had secured the premises after the fire and he opened the premises for the fire marshal on the Monday after the fire. It also claims that the defendant’s attorney called the landlord to gain access to the building.30 The defendant argues that the police were not at all mistaken as to the essential facts. They knew that Cipriano owned the premises but that it was currently occupied by the defendant. Detective Lieutenant Solomita was one of the two officers [252]*252dispatched to Cipriano’s home to seek his consent to enter the premises; Solomita lived in the area of the defendant’s pizza business and had even been a patron there prior to the fire.31 At that time Solomita knew the defendant was a suspect. When they entered for the search, after Cipriano pried off the plywood on the front door, the defendant’s equipment was still there; they initially saw it there eleven days earlier when police and fire officials were there with the defendant as well as Cipriano. He stresses the lack of exigent circumstances stating that the fire had long since been extinguished.
In Stoner, the United States Supreme Court said that “the rights protected by the Fourth Amendment are not to be eroded by strained applications of the law of agency by unrealistic doctrines of ‘apparent authority.’ ” Stoner v. California, supra, 488. Some courts have refused to suppress evidence obtained as the result of a reasonable good faith belief that permission was given by one with the actual authority to consent to a search. See People v. Adams, 53 N.Y.2d 1, 8-9, 422 N.E.2d 537 (1981), and cases there cited. The rationale for this approach has been said to derive from the fact that the fourth amendment protects against unreasonable searches and seizures and, therefore, “if the police are acting in a reasonable fashion in response to the circumstances with which they are confronted, then an error in judgment in failing to ascertain the actual authority of the person to consent should not give rise to an unreasonable search.” People v. Adams, supra, 9. It is true that implicated in this [253]*253rationale is the purpose of the exclusionary rule. That rule was designed “to deter future unlawful police conduct and thereby effectuate the guarantee of the Fourth Amendment against unreasonable searches and seizures” and not primarily to vindicate the individual’s constitutional right. United States v. Calandra, 414 U.S. 338, 347, 94 S. Ct. 613, 38 L. Ed. 2d 561 (1974); People v. Adams, supra, 9. We do not dispute, assuming we adhered to the rule the state urges us to adopt, the view that application of the exclusionary rule in a case where there existed reasonable good faith reliance by the police would do little in discouraging improper police conduct. We deem relevant, at this point, the following language from Adams: “We emphasize that the police belief must be reasonable, based upon an objective view of the circumstances present and not upon the subjective good faith of the searching officers. Moreover, a warrantless search will not be justified merely upon a bald assertion by the consenting party that they possess the requisite authority. Nor may the police proceed without making some inquiry into the actual state of authority when they are faced with a situation which would cause a reasonable person to question the consenting party’s power or control over the premises or property to be inspected. In such instances, bare reliance on the third party’s authority to consent would not be reasonable and would, therefore, subject any such search to the strictures of the exclusionary rule.” People v. Adams, supra, 9-10; see People v. Wagner, 114 Mich. App. 541, 548-49, 320 N.W.2d 251 (1982). If we apply these principles to this case, the trial court could have reasonably concluded that the officers did not demonstrate the necessary reasonable good faith belief under the [254]*254circumstances. Therefore, we need not decide whether such an exception to the exclusionary rule exists.32 The state does not claim that there was no evidence upon which the trial court could base the decision it reached, but rather that the result was erroneous under the applicable law. It is correct that the evidence was often in conflict and, arguably, the decision was a close judgment call, but credibility is still the province of the trier. Assuming arquendo that probable cause existed for the issuance of a warrant on February 13, as the state argued before us, we must observe that courts have strongly supported the preference to be accorded searches under a warrant and have explicated that a doubtful or marginal case with a warrant may be sustainable where one without it would fail. See, [255]*255e.g., United States v. Ventresca, 380 U.S. 102, 106, 85 S. Ct. 741, 13 L. Ed. 2d 684 (1965); Jones v. United States, 362 U.S. 257, 270, 80 S. Ct. 725, 4 L. Ed. 2d 697 (1960); State v. Bember, 183 Conn. 394, 412, 439 A.2d 387 (1981); State v. Jackson, 162 Conn. 440, 445, 294 A.2d 517, cert. denied, 409 U.S. 870, 93 S. Ct. 198, 34 L. Ed. 2d 121 (1972). One of the purposes of the warrant requirement “is to prevent hindsight from coloring the evaluation of the reasonableness of a search or seizure.” United States v. Martinez-Fuerte, 428 U.S. 543, 565, 96 S. Ct. 3074, 49 L. Ed. 2d 1116 (1976). Just as a search cannot be justified by the potent evidence it produces, so also an unlawful search cannot be justified by claiming that the evidence seized might have been obtained by other and lawful means. United States v. Mancusi, 379 F.2d 897, 903 n.9 (2d Cir. 1967), aff’d sub nom. Mancusi v. DeForte, 392 U.S. 364, 88 S. Ct. 2120, 20 L. Ed. 2d 1154 (1968). The state has not shown, as it must, [256]*256that the trial court’s conclusions in this case were “clearly erroneous.” See State v. Ostroski, supra; Pandolphe’s Auto Parts, Inc. v. Manchester, supra; Practice Book § 3060D. It follows from what we have said that this search and seizure was “unreasonable” under the fourth amendment.
There is no error.
