Opinions

McKUSICK, Chief Justice.

Plaintiffs, individual users of Baxter State Park,¹ and intervenor Natural Resources Council of Maine challenge the legality of Park Rule 19,² a regulation issued by defendant Baxter State Park Authority that permits limited use of snowmobiles by members of the public for access to the Park in the wintertime.³ Basically, Rule 19 permits snowmobiles to travel only on the perimeter road, so-called, one of the Park roads open to automobiles in the summertime. See the map attached to this opinion as Appendix A. On appeal from the Superior Court (Kennebec County), which upheld Rule 19, appellants argue that the rule is invalid because it violates the terms and purposes of the Baxter State Park Trust and because it was not adopted by a unanimous vote of the three members of the Authority. We deny the appeal and affirm the judgment.

I. Background

A. The Park

Baxter State Park consists of lands deeded between 1931 and 1962 by former Governor Percival Baxter to the State and administered pursuant to a unique charitable trust.⁴ No single document sets forth the terms of the Baxter State Park Trust (the trust). Instead, the trust evolved over time to reflect Governor Baxter’s intent as embodied in his deeds⁵ and transmittal letters.⁶ The deeds conveyed land to the State in trust for the benefit of the people of Maine, subject to two conditions: first, that the Park lands “forever shall be kept for and as a State forest and public park and for public recreational purposes;” and second, that they “forever shall be kept in their natural and wild state and as a sanctuary for wild beasts and birds _”⁷ (Emphasis added) In 1955 Governor Baxter executed a formal declaration (which was accepted by the legislature in the 1955 Interpretation Act, P. & S.L. 1955, ch. 2) designed to amplify his intent and clarify the terms of the trust. In that instrument he declared his views on the interrelationship between the two key trust conditions, as follows: “This area [the Park] is to be maintained primarily as a Wilderness and recreational purposes are to be regarded as of secondary importance and shall not encroach upon the main objective of this area which is to be ‘Forever Wild.’ ” Id. The same 1955 Interpretation Act confirmed the authority of the State to build access roads in the Park, carrying out Governor Baxter’s earlier decision, reflected in P. & S.L. 1949, ch. 2, to make the Park “more accessible for public use and enjoyment.” That 1949 statute gave discretion to the State as trustee to build and maintain access roads as it “shall deem to be in the public interest and for the proper use and enjoyment” of the public on the condition that the roads be “constructed and maintained in a manner not to interfere with the natural wild state now existing ....” Id.

The Baxter State Park Authority administers the Park in accordance with the terms of the trust.⁸ 12 M.R.S.A. §§ 900-907 (1981 & Supp. 1985-1986). Its membership consists of the Attorney General, the Director of the Bureau of Forestry, and the Commissioner of the Department of Inland Fisheries and Wildlife. 12 M.R.S.A. § 901 (Supp. 1985-1986). Although the Authority is an agency of the State, it operates in a manner different from any other state agency. Its members “must administer the trust like any private trustees of a charitable trust, exercising their best judgment, informed by the Attorney General’s advice on any legal question and, where necessary, by instructions of a court of equity.” Fitzgerald v. Baxter State Park Authority, 385 A.2d 189, 202 (Me.1978).

B. History of Park Rule 19

Prior to 1968, snowmobile use in the Park was unregulated. In December 1968, shortly before Governor Baxter’s death, the Authority promulgated its first regulation regarding snowmobiles. That version of Rule 19 permitted use of snowmobiles on the perimeter road, some connecting service roads, and certain trails. It remained substantially unchanged for the next eight years.

In 1976 the Attorney General gave the Authority his legal opinion that the trust prohibits any and all use of snowmobiles in the Park except for administrative and emergency uses. Op.Me.Att’y.Gen. (May 20, 1976). The Authority amended Rule 19 to comply with that opinion. That rule remained in effect until 1981.

In November 1979, the Authority decided to reconsider the 1976 version of Rule 19 and voted to petition the Superior Court for instructions on several issues concerning the legality of permitting snowmobiles access to the Park. On September 11, 1980, the Authority agreed that if the Superior Court ruled that it was within the Authority’s discretion to permit use of snowmobiles, it would initiate a rulemaking proceeding to establish the appropriate scope of such use in the Park. The next day the Authority filed its petition in the Superior Court.⁹

Several individuals and organizations, including the Natural Resources Council of Maine, intervened in the proceeding before the Superior Court. By stipulation of the parties, the petition was narrowed to seek a declaratory judgment on a single question that the Superior Court justice in his later opinion framed as follows:

The issue presented is whether, as a matter of law, based upon Governor Baxter’s intent as expressed in the trust documents and other extrinsic evidence relating thereto, the Authority is prohibited from allowing snowmobiles in the park. This Court is not called upon to decide, nor does it purport to decide, the issue of whether snowmobile use should be permitted but only whether the intent of Governor Baxter is so clear as to permit the Court to rule as a matter of law that such use is prohibited.

The litigants amassed an impressive record, containing depositions, affidavits, a compilation of Governor Baxter’s correspondence, and testimony of several witnesses, all on the Governor’s intent and the effects of snowmobile use on the physical environment and on other users of the Park.

The Superior Court in June 1981 issued its declaratory judgment that the Authority “is not prohibited as a matter of law by the Baxter Park Trust from permitting the use of snowmobiles in the park for recreational purposes.” ¹⁰ In reaching that conclusion, it found that the Governor’s paramount purpose in establishing the Park was to “create and preserve an area in which persons could have a wilderness experience.” The Governor’s secondary objective was “that the area be reasonably accessible.” The court held that the use of snowmobiles promotes that trust objective of access. It also held that any access by snowmobiles is not a per se violation of the “forever wild” trust condition. Although Governor Baxter’s two objectives could be accommodated, the court’s opinion stressed that “[i]t is equally clear that while these dual purposes exist, the preservation of the wilderness takes priority over access .... ” This declaratory judgment (hereinafter referred to as the 1981 judgment) was never appealed.

II. The Current Version of Rule 19

In September 1981 the Authority initiated the rulemaking proceeding that led to adoption of the current version of Rule 19, the subject of the present appeal.¹¹ At a series of public hearings held in Augusta, Millinocket, Orono, and Portland, it heard testimony from representatives of the Appalachian Mountain Club, Maine Audubon Society, Maine Snowmobile Association, Natural Resources Council of Maine, and Sierra Club, as well as legislators and private citizens. It also solicited written comments and discussed the issue at an open meeting with the Park staff. On December 22, 1981, by a vote of 2-1, the Authority adopted the present Rule 19. That rule allows members of the public to travel by snowmobiles on most of the Park’s perimeter road on the southern, western, and northern sides of the Park, and on the Telos cut-off road on the western edge of the Park, both roads being open to automobile use in the summertime. The rule also permits travel by snowmobile on Mataga-mon and Webster Lakes, boundary lakes that lie only partly within the Park; and along two short stretches of the East Branch of the Penobscot River, near the Park’s northerly and northeasterly boundaries. Snowmobiles are expressly excluded from the Park roads into South Branch, Kidney, and Daicey Ponds, and into Roaring Brook. All of those roads are open to automobiles in the summertime. The rule confines snowmobiles to the unplowed (i.e., traveled) portions of the perimeter and Te-los cut-off roads. Everywhere else in the Park, including the vast eastern and interi- or areas of the Pa^k, the use of snowmobiles is prohibited.¹² See the full text of Rule 19, n. 2 above, and the map in Appendix A.

Plaintiffs promptly sought judicial review of Rule 19 by the Superior Court. Their complaint raised three contentions. First, it tried to reopen the issue decided by the Superior Court in the 1981 proceeding, namely, whether any use of snowmobiles in the Park violates the trust. Second, it made a general attack on the design of Rule 19, asserting that the extent to which the rule permits travel by snowmobiles in the Park constitutes an abuse of discretion and violates the trust. Third, it made a specific attack on the rulemaking proceeding, contending that the rule was invalid because it was not adopted by a unanimous vote of the Authority’s members. The record before the Superior Court included the evidence received in the court’s prior snowmobile proceeding and the presentations to the Authority in its 1981 rulemak-ing proceeding. In April 1985 the Superior Court denied appellants’ appeal and sustained the validity of Rule 19. It held that the 1981 judgment bars relitigation of the general proposition that as a matter of law the trust does not exclude any and all use of snowmobiles in the Park; that the Authority did not abuse its discretion in promulgating Rule 19;¹³ and that the Authority is empowered to exercise its rulemaking function by majority vote. The Natural Resources Council of Maine and three individual plaintiffs took timely appeals to this court.

III. Validity of Rule 19 A. Compliance with the Trust

The central issue on appeal to this court is whether Rule 19 goes too far in allowing the use of snowmobiles in the Park. We do not consider the legal question whether any use of snowmobiles¹⁴ in the Park is barred by the Baxter State Park Trust. That question was answered in the negative, once and for all, by the 1981 judgment of the Superior Court. Collateral estoppel now bars relitigation of that question.¹⁵ Our analysis must start, therefore, from the premise that, as a matter of law, the Authority is not prohibited from promulgating a rule that allows access to the Park by snowmobiles.

Our analysis must also recognize that, as the 1955 Interpretation Act, P. & S.L. 1955, ch. 2, makes clear, the “forever wild” condition of the trust takes precedence over Governor Baxter’s secondary goals of access and recreation. Although the wilderness purpose is superior to that of access, it does not preclude all manner of access to the Park. Reasonable access, when properly balanced with the paramount objective of preserving the wilderness experience, is a trust purpose that the Authority is charged to promote.

The Authority correctly viewed the 1981 judgment as the starting point for its rule-making proceeding. “The [1981 judgment] concluded that these objectives [access and wilderness] are legally compatible. Our task, as we see it, is to determine whether this is so as a practical matter, should we decide to allow snowmobiles in the Park.” (Emphasis added) The Authority also recognized that any rule it chose to promulgate may not permit the use of snowmobiles to encroach on the wilderness experience of other users of the Park, principally cross-country skiers and snowshoers. It stated that “if there is a[n] irreconcilable conflict between the use of snowmobiles and the wilderness experience of others in the Park — if the two cannot co-exist in the 200,000 acre Park — then snowmobiles should be excluded from the Park.” Within that legal framework the Authority sought to craft a rule that permits access to the Park by snowmobiles and yet preserves the wilderness experience in the Park for cross-country skiers and snow-shoers.

The critical issue before this court is whether the manner and extent to which Rule 19 allows snowmobiles in the Park exceeds the scope of the discretion vested in the Authority by the Baxter Trust. Judicial review of the Authority’s rulemaking is governed by the Administrative Procedure Act, 5 M.R.S.A. § 8058 (1979 & Supp. 1985-1986), which provides in pertinent part:

Insofar as the court finds that a rule was improperly adopted or exceeds the rule-making authority of the agency, it shall declare the rule invalid. If the court finds that the rule was properly adopted and not in excess of the agency’s rule-making authority, its substantive review of that rule shall be to determine whether the rule is arbitrary, capricious, an abuse of discretion or otherwise not in accordance with law.

(Emphasis added) The law to be applied by this court, set forth in 12 M.R.S.A. § 903, requires that Rule 19 must be consistent with “the proper observance of the conditions and restrictions expressed in the deeds of trust of the park to the State.” See n. 8 above. The 1981 judgment has already construed those deeds of trust to the extent of declaring that they do not as a matter of law bar wintertime access to the Park by snowmobiles.

The Authority took special care to explain the factual basis and rationale of Rule 19. Based on an exhaustive review of all the evidence assembled in the 1981 Superior Court case and during the subsequent agency rulemaking proceeding, the Authority reached three conclusions. First, it determined that the Park should be accessible in winter and that snowmobiles provide a reasonable method of winter access. That finding was grounded on the testimony of the snowmobile proponents to the effect that to allow snowmobiling would increase the recreational use of the Park; that it would enable some citizens to visit the Park who otherwise would be denied access in the wintertime; that modem snowmobiles are quieter than earlier models; and that snowmobilers are courteous to other users of the same trails. In sum, evidence of record demonstrates that Rule 19 promotes the trust objective of access and recreation in the Park. Second, the Authority found that “the use of snowmobiles on the perimeter road will [not] adversely affect wildlife or otherwise affect the physical status of the Park,” a finding that is not challenged on appeal to this court.

The critical decision, then, turned on the Authority’s judgment as to the manner and extent to which the use of snowmobiles should be allowed in order to promote access without encroaching upon the primary goal of preserving the wilderness experience. Snowmobile opponents testified before the Authority to the effect that the use of snowmobiles would deprive them of the wilderness experience they seek in the Park. Because the nature of a “wilderness experience” is highly subjective, the Authority accorded special respect to those views. “We acept the heartfelt testimony and letters from cross-country skiers and snowshoers that snowmobiles would infringe upon their wilderness experience in the Park. Governor Baxter ... intended to make the Park accessible, but the access he intended was for the paramount purpose of providing a wilderness experience.” The Authority concluded, however, that the Park could accommodate diverse winter activities and that by strictly confining snowmobiles, principally to the perimeter road, the wilderness experience could be preserved for cross-country skiers and snow-shoers. Upon reviewing those conclusions, the Superior Court held:

By thus giving preservation of the wilderness experience priority over enhanced access during the winter months, the Authority stayed within the boundaries [of] its discretion as the trustee of the Park. By permitting restricted recreational snowmobile use, Rule 19 greatly enhances the Park’s accessibility in the wintertime without unduly infringing on the wilderness experience of other, nonmechanized users of the Park.

We accord no special deference to that ruling of the Superior Court, sitting as it was as only an intermediate appellate tribunal. Instead we review Rule 19 independently in light of the record before the Authority. See Gulick v. Board of Environmental Protection, 452 A.2d 1201, 1209 n. 6 (Me.1982). Nonetheless, we come to the same conclusion as the Superior Court.

Rule 19 represents a rational accommodation between the dual goals of the Baxter State Park Trust. Because the rule subordinates the objective of wintertime access by snowmobiles to Governor Baxter’s predominant purpose of wilderness preservation, it is consistent with the terms and purposes of the trust. Nothing in this record causes us to second-guess the judgment of the Authority. Rule 19 strictly limits the use that may be made of snowmobiles for wintertime access to the Park. It confines use of snowmobiles principally to the perimeter road. By contrast, use of automobiles in the summertime is permitted not only on the perimeter road but also on several other roads of the Park.

Rule 19, while enhancing wintertime access to the Park, at the same time protects the public’s opportunity to enjoy the wilderness experience. It entirely prohibits snowmobile use in the vast eastern and interior two thirds of the Park. That area, the Authority found, is the part of the Park favored by cross-country skiers and snow-shoers seeking a wilderness experience.¹⁶ “Once the skiers and the snowshoers leave the perimeter road,” the Authority concluded, “they will not hear, see or smell any snowmobiles. This group, then, will have access to the vast interior of the Park, including the roads and trails most popular for skiing and snowshoeing, with no infringement upon their wilderness experience.” In designing Rule 19 the Authority succeeded in preserving the wilderness experience that Governor Baxter intended to protect as the primary objective of the trust.

Governor Baxter could not be expected to have fully anticipated the exact nature of the conflicts between his wilderness and access goals that are presented by such facts of present-day life as the use of snowmobiles.¹⁷ With customary wisdom he left it to the Authority to accommodate his twin objectives in the face of such conflicts. The Governor vested the Authority with the responsibility of exercising its best judgment in working out conflicts with solutions that promote both objectives of the trust, but gives priority to Governor Baxter’s goal of maintaining the Park “forever wild.”

The importance of the task that Governor Baxter committed to the Authority’s judgment is shown by the keen interest he took in the composition of the Authority's membership. See generally Op.Me.Att’y Gen. 83-46. “The membership in the Authority, obviously selected by Governor Baxter himself and ratified by him by his subsequent gifts, consists of the State’s principal officers in the professions of the law, forestry, and fish and wildlife management. Both Governor Baxter and the Legislature placed their confidence in the judgment and integrity of those high state officials.” Fitzgerald v. Baxter Park Authority, 385 A.2d at 202-03. In discharging their duties, the members of the Authority often have to grapple with issues such as the snowmobile controversy that the trust does not resolve or that require application of specialized and technical expertise. Those situations require the Authority to exercise its best judgment, informed by its own careful study of the documentary evidence and by court decision and public comment, in order to discern and implement Governor Baxter’s vision for the Park. Thus, “even though the Baxter trust is not a discretionary one, the expert judgment of members of the Park Authority ... should generally be accorded great weight in choice of methods for carrying out the donor’s intent.” Id. at 202. In the case at bar there is no legal justification for disturbing the in-depth study and expert judgment of the Authority in defining the appropriate use of snowmobiles in the Park. Rule 19 represents a permissible exercise of judgment by the Authority.

Of the many questions that the Authority addressed in promulgating Rule 19, appellants single out for special attention the issue whether Rule 19’s restrictions on snowmobiling are enforceable. On appeal they contend that Rule 19 is fatally defective because some snowmobilers may use the perimeter road and the Telos cut-off merely as an easy way to get from one side of the Park to the other. All parties agree that Governor Baxter intended the Park to be a destination rather than a detour or shortcut. The Authority recognized the thoroughfare problem but found no evidence to portend significant violation of the rule. It concluded “that there is no legitimate basis for assuming that snowmobile[r]s will abuse the rule any more than others [i.e., motorists] do_" Appellants properly point out that the fact that some automobiles may use the Park as a summertime thoroughfare cannot save Rule 19. There is no evidence, however, that in the time Rule 19 has been in effect, snowmobiles have used the Park’s perimeter road as a mere thoroughfare. The Authority committed itself to monitoring the rule and can be expected to address by appropriate measures any significant problems that may arise.¹⁸ In the meantime, the speculative possibility of abuse of Rule 19 does not invalidate it.

B. Validity of the Authority’s Majority Vote

The statute governing composition of the Authority, 12 M.R.S.A. § 901, provides in part: “[The Park] shall be under the joint supervision and control of, and shall be administered by the Director of the Bureau of Forestry, the Commissioner of Inland Fisheries and Wildlife and the Attorney General.” (Emphasis added) Appellants urge that “joint supervision and control” means that the Authority cannot take any action, such as adopting a rule, unless all of its members agree. To support their argument they point, however, only to the adjective “joint,” and do not offer any persuasive rationale for that interpretation.

The legislature has enacted rules of construction that expressly define the requirements of decisionmaking by three or more persons in legislatively created commissions and similar bodies. “Words giving authority to 3 or more persons authorize a majority to act, when the enactment does not otherwise provide.” 1 M.R.S.A. § 71(3) (1979) (emphasis added). The term “joint supervision and control” does “not otherwise provide”; it merely declares that all three heads of the relevant state agencies shall participate in voting on questions of the supervision and control of the Park. If the legislature meant to require unanimity in such voting, contrary to the statutory canon of construction, it easily could have so provided. Instead, it directed the three-member Authority to promulgate rules in accordance with the Administrative Procedure Act, exactly the same as any other multi-member state board. See n. 8 above. Nothing in that act can be construed to require a unanimous vote for the valid promulgation of a rule by a state agency.

The entry is:

Judgment affirmed.

1 . Of the seven original plaintiffs in this action, only Roger Normand, James Haddow, and David Tyler appeal the judgment of the Superior Court.

2 . Baxter State Park, Rules and Regulations No. 19 (Rev.1982) provides in full:

SNOWMOBILES: Snowmobiles may be used on Matagamon and Webster Lakes and on the unplowed portions of the regular road system currently maintained by the Department of Transportation for vehicular traffic in the summer, excluding, however, the portion of the Park Perimeter Road, not presently in use, passing by Dwelley Pond. Snowmobiles also shall not be allowed on the roads into South Branch Pond, Roaring Brook, Daicey Pond, Kidney Pond, and the tote road into Katahdin Lake from Avalanche Field, but shall be allowed on the one-half mile section over the easterly projection of Baxter Park in Township 6, Range 8 along the west side of the East Branch of the Penobscot River, a one-mile section along the East Branch of the Penob-scot River in Township 6, Range 9 from the westerly end of Second Lake Grand Mataga-mon, and the Telos cut-off road from the Telos Gatehouse to the Park Perimeter Road via Morse Mountain. Use of all other roads, lakes and trails or any other portion of the Park by snowmobiles is prohibited, except by authorized personnel on Park business. Operators travel at their own risk and must comply with all requirements of State laws and drive safely at all times. Operation by persons under 10 years of age is prohibited.

3 . This opinion will discuss only the use of snowmobiles in the Park by members of the public, and not their use, as permitted by Rule 19, “by authorized personnel on Park business.” None of the parties contest the legality of the latter administrative or emergency use.

4 . Fitzgerald v. Baxter State Park Authority, 385 A.2d 189, 191-92 (Me.1978), describes the history of the Park as follows:

Among the many public-spirited benefactors with whom the State of Maine has been blessed, Percival Proctor Baxter stands preeminent. In its combination of size, uniqueness, permanence, and vision, his gift of Baxter State Park to the people of Maine has no equal. Over a period of 31 years, former Governor Baxter deeded to the State of Maine in trust a total of 201,018 acres of land, principally in Piscataquis County, for the establishment of Baxter State Park. His first gift in 1931 of about 6,000 acres, encompassing the higher areas of Mt. Katahdin and the slopes on all four sides, set a pattern that he was to follow in his succession of gifts completed in 1962. In each case he transmitted to the current governor his deed of trust which was then duly submitted to the legislature for acceptance by private and special act. In Governor Baxter’s transmittal letters to the successive governors, he set forth his grand design for a state park around Maine's highest mountain. In addition to the conveyances of land, Governor Baxter in 1961 and 1965 gave the State sums in excess of $1.5 million for the care, operation, and maintenance of the Park. P. & S.L. 1961, ch. 21; P. & S.L. 1965, ch. 30.

(Footnotes omitted)

5 . For the deeds and acceptances, see Private and Special Laws: 1931, ch. 23; 1933, ch. 3; 1939, chs. 1, 122; 1941, chs. 1, 95; 1943, chs. 1, 91; 1945, ch. 1; 1947, ch. 1; 1949, chs. 1, 2; 1955, chs. 1, 3, 61, 171; 1963, ch. 1.

6 . By this method of conveyance, Governor Baxter intended to create an evolving trust that reaffirmed his vision of the Park. "In this manner a long list of precedents is being established; precedents which, as time passes, will show that eight or ten different Governors and as many Legislatures, by laws duly passed and signed by these Governors, have entered into solemn pacts that create a succession of irrevocable trusts.” Laws of Maine, 1943, p. 701. For the transmittal letters, see Laws of Maine as follows: 1931, pp. 725-26; 1933, p. 859; 1939, pp. 846-47; 1941, pp. 760-61; 1943, pp. 698-708; 1945, pp. 982-90; 1947, pp. 1244-45; 1949, pp. 1368-70; 1955, pp. 1143-50; 1963, p. 1473.

7 . Each of the deeds and acceptances listed in note 5 above contains both conditions except that P. & S.L. 1955, chs. 61 & 171, omit the second, "forever wild" condition. Instead, both of those deeds conveyed certain lands in trust on the condition that the lands "shall forever be held for and as a State forest, public park, and public recreational purposes and for the practice of Scientific Forestry ...."

8 . The legislature mandates that "it shall always be the purpose of the Authority to satisfy the terms of the Trust.” 12 M.R.S.A. § 900 (1981). The Authority exercises "full power in the control and management” of the Park and may receive trust funds and collect fees "for maintenance and operation of the Park.” 12 M.R.S.A. § 901 (Supp.1985-1986). It may promulgate rules consistent with the Administrative Procedure Act that "it deems necessary for the protection and safety of the public or for the proper observance of the conditions and restrictions expressed in the deeds of trust of the Park to the State." 12 M.R.S.A. § 903 (1981). It also exercises police powers over the Park, 12 M.R.S.A. § 905 (1981), and may hire agents to discharge its duties. 12 M.R.S.A. § 904 (1981).

9 . The Authority’s petition invoked the Superior Court’s jurisdiction pursuant to the Declaratory Judgments Act, 14 M.R.S.A. §§ 5953, 5956(2), (3) (1980), and the court's equity jurisdiction pursuant to 14 M.R.S.A. § 6051(10), (13) (1980).

10 . In a footnote hung on the word "recreational” in his declaratory judgment, the Superior Court justice explicitly defined what he meant by "the use of snowmobiles in the park for recreational purposes”:

The term recreational is used herein in contrast to the administrative or emergency use of snowmobiles. The potential use discussed by the counsel in this proceeding could best be described as access by snowmobiles on the portions of the park road system.... It is not within the contemplation of any of the parties that snowmobiles would be allowed to frolic at will throughout the park anymore than automobiles are permitted to do so during the summer season.

11 . The Authority is authorized to promulgate rules in accordance with the Administrative Procedure Act. See 5 M.R.S.A. §§ 8051-8058 (1979 & Supp. 1985-1986). See n. 8 above.

12 . In a lengthy “Factual and Policy Statement for Rule 19 (Snowmobiles)," the Authority set forth the evidence and rationale that support Rule 19. The Director of the Bureau of Forestry dissented and filed a separate statement.

13 . The Superior Court erroneously stated that its review of Rule 19 was pursuant to 5 M.R.S.Á. § 11007 (1979), which governs judicial review of final agency action. Agency rules, however, are to be reviewed pursuant to 5 M.R.S.A. § 8058 (1979 & Supp.1985-1986). Despite the different statutory authorization for review, the analysis is essentially the same, requiring the court to test the legal and factual basis for the agency action. See Cumberland Farms Northern, Inc. v. Maine Milk Comm'n, 428 A.2d 869, 873-74 (Me.1981).

14 . See n. 3 above.

15 . On appeal appellants concede that principles of collateral estoppel preclude relitigation of the issue decided by the Superior Court in the 1981 proceeding. The Authority, which pleaded, proved, and preserved its claim of collateral estoppel, invokes the doctrine as an affirmative defense against appellants on both a mutual and a nonmutual basis. Intervenor Natural Resources Council of Maine was a party to the 1981 proceeding; plaintiffs were not, although their interests were well represented by similar individual users of the Park. The key legal issue "whether the Authority is prohibited ... from permitting the use of snowmobiles within the Park for recreational purposes,” was fully and fairly litigated and a final, binding judgment entered. That issue could have been reconsidered only on direct appeal from the 1981 judgment. Appellants lost that opportunity when no appeal was taken from that 1981 judgment. See Spickler v. Flynn, 494 A.2d 1369, 1373 (Me.1985) (per curiam); Hossler v. Barry, 403 A.2d 762, 766-68 (Me.1979).

16 . The Authority explained the basis of this finding as follows:

We heard testimony that, for the most part, cross-country skiers and snowshoers enter the Park from the Togue Pond gate at the southern end of the Park, and then travel to Roaring Brook, then Russell Pond, and on to South Branch Pond or enter from the north at the Matagamon Gate and travel down through South Branch Pond.... [E]xcept for the short distances on the perimeter road between the Togue Pond gate and the Roaring Brook Road in the south and the Trout Brook crossing and the Matagmon Gate in the north, there will be a total separation of uses between snowmobiles, and cross-country skiers or otherwise with the rule we adopt.

17 . Prior to his death in 1969, Governor Baxter in a 1965 letter to Helen Taylor wrote the following in regard to "Motor Skis”: "I would be much pleased if the AUTHORITY would add this to the list of what is forbidden in the regulations.” As the Superior Court in its opinion accompanying the 1981 judgment stated, "While the [1965] letter expresses the settlor’s then current view of snowmobiles, it also acknowledges the power of the Authority to regulate their use.”

18 . The Authority warned that it will not tolerate violation of the rule. “If we discover that the rule is not being obeyed, we will change it to exclude snowmobiles.”
