MEMORANDUM FINDINGS OF FACT AND OPINION
PANUTHOS, Special Trial Judge: Petitioner's Motion to Compel Respondent to Answer More Fully Petitioner's First Set of Interrogatories and Request for Production of Documents, filed September 22, 1986, was assigned for hearing, consideration and ruling, thereon. 1 Respondent, in his notice of deficiency dated April 11, 1985, determined a deficiency in petitioner's Federal income tax for the taxable year 1982 in the amount of $22,061.59. 2 A timely petition was filed on July 15, 1985. (The petition was mailed on July 9, 1985.) 3
In its discovery request, petitioner seeks information relating to the question of whether the notice of deficiency was issued to petitioner's last known address. Respondent has objected to a substantial portion of petitioner's discovery request. The basis of respondent's objection is that the requested discovery is not relevant since, as a matter of law, the last known address question is not a proper issue in this case. Respondent argues in the alternative that the discovery request is duplicative, unduly burdensome and overly broad. Petitioner argues that the two principal issues in this case are: (1) whether a valid statutory notice has been issued in this case and (2) if a valid notice of deficiency was issued whether the notice was sent to petitioner's last known address. Since the parties appear to agree that the requested discovery relates only to the issue of whether the statutory notice of deficiency was sent to petitioner's last known address, we look to determine whether, based on the facts in the present record, we can determine as a matter of law, that there is no genuine issue of material fact relating to this matter.
Our first consideration is to determine whether or not petitioner has made a proper request for discovery and, if so, determine whether we should sustain respondent's objections thereto. The purpose of discovery is to reduce surprise by providing a means by which the parties can obtain knowledge of relevant facts in sufficient time to perfect a record for purposes of trial. 4 A party's right to discovery is determined by reference to principles of relevancy and materiality as set forth in Rule 70 which is derived generally from the Federal Rules of Civil Procedure. Davis v. Commissioner,69 T.C. 716, 720 (1978). The standard of relevancy is somewhat liberal. Zaentz v. Commissioner,73 T.C. 469, 471 (1979); P.T. & L. Construction Co. v. Commissioner,63 T.C. 404, 413-414 (1974). Rule 70(b) permits discovery on the entire subject matter of the case and not merely as to the issues of the pending case. Zaentz v. Commissioner,supra.The burden of establishing that the documents or responses sought are not relevant or otherwise discoverable is on the party opposing production. Rosenfeld v. Commissioner,82 T.C. 105, 112 (1984); Rutter v. Commissioner,81 T.C. 937, 948 (1983); P.T. & L. Construction Co. v. Commissioner,supra.
Since the parties agree that the request for discovery 5 relates only to the question of the last known address we consider that issue as it relates to the relevancy of the discovery.
Petitioner alleges in its petition and in other documents that the notice of deficiency was not sent to petitioner's last known address and that respondent's agents failed to otherwise timely notify petitioner of the deficiency.6 For purposes of our opinion herein, we assume those facts most favorable to petitioner. Accordingly, to properly consider respondent's objection to discovery we assume that the requested discovery could lead to facts which would cause us to conclude that the notice of deficiency was not sent to petitioner's last known address as that term has been judicially defined. See Frieling v. Commissioner,81 T.C. 42, 49 (1983) and cases cited therein.
The question of petitioner's "last known address" usually arises either because of (1) a jurisdictional defect (untimely petition and claim by the taxpayer that the notice of deficiency was not sent to the last known address, e.g., Alta Sierra Vista, Inc. v. Commissioner,62 T.C. 367, 372 (1974), affd. without published opinion 538 F.2d 334 (9th Cir. 1976)) or (2) a statute of limitations claim (taxpayer's claim that the notice of deficiency which was not sent to the last known address did not toll the statute of limitations, e.g., Reddock v. Commissioner,72 T.C. 21 (1979); Frieling v. Commissioner,supra.).
We first consider the jurisdictional question. There is no dispute that a timely petition was filed in this case. In this regard, "It has been held repeatedly that an error in the address to which the notice of deficiency is mailed does not render the notice invalid so as to defeat Tax Court jurisdiction where the petition is timely filed." Mulvania v. Commissioner,81 T.C. 65, 68 (1983). 7 Accordingly, the validity of the notice of deficiency cannot be attacked on the ground that it was not sent to petitioner's last known address since a timely petition was filed. Mulvania v. Commissioner,supra;Gray v. Commissioner,73 T.C. 639, 645 (1980). 8
Petitioner relies on Reddock v. Commissioner,supra for the proposition that a notice of deficiency which is erroneously addressed and undelivered is not valid for any purpose. Respondent on the other hand argues that petitioner misconstrues Reddock. We agree with respondent. In Reddock, the notice of deficiency was issued to the taxpayer shortly before the statute of limitations was due to expire. The notice was returned to the Internal Revenue Service as undeliverable and remailed at a date after the three-year statute of limitations had expired. The taxpayer upon receipt of the second mailing of the notice of deficiency filed a petition with the Court within 90 days of the second issuance of the notice of deficiency. The taxpayer moved to dismiss on the ground that the assessment of a deficiency was barred by the statute of limitations. The Court held that the assessment was barred since the notice of deficiency was not remailed to the taxpayers until after the period of limitations had expired. 9
The tax year in issue in this case is 1982. The notice of deficiency was issued on April 11, 1985. A timely petition was filed. Since the return was due to be filed on April 15, 1983 the normal three-year statute of limitations would expire on April 15, 1986 assuming the return was filed on or before that date. 10 Section 6501(a). Thus, since the notice of deficiency was timely issued on April 11, 1985 and received by petitioner there is no statute of limitations issue present in this case. 11
We are unaware of any information that petitioner could obtain through discovery which would cause a different result herein. Accordingly, since we have found that there is no genuine issue or matter regarding the last known address of the notice of deficiency, and as a matter of law we have jurisdiction in this case, petitioner's discovery request is not relevant or material to any issue or subject matter of this litigation. Thus, petitioner's Motion to Compel, filed September 22, 1986, will be denied.
An appropriate order will be issued.
