78 T.C. 320">*320 OPINION

Respondent determined a deficiency in petitioner's Federal1982 U.S. Tax Ct. LEXIS 132">*134 estate tax of $ 7,296. After concessions, the sole issue to be decided is whether petitioner may deduct $ 3,000 from the date-of-death value of each of eight gifts made by Jane B. Ceppi, now deceased, on January 5, 1978, 10 days before her death.

This case was submitted fully stipulated pursuant to Rule 122. ¹ The stipulation of facts is incorporated by this reference.

Petitioner is the Estate of Jane B. Ceppi, represented by its 78 T.C. 320">*321 executor, Peter B. Ceppi. At the time he filed the petition in this case, Peter B. Ceppi resided in Jamestown, R. I. Jane B. Ceppi died on January 15, 1978, in Jamestown, R. I. Ten days previously, she made eight gifts to eight different relatives. Each gift consisted of 75 shares of Dome Mines stock and 20 shares of Texas Instruments, and each gift1982 U.S. Tax Ct. LEXIS 132">*135 had a value of $ 6,477.75 on January 5, 1978, and a value of $ 6,585.00 on January 15, 1978.

The parties agree that the value of the stock transferred by the decedent 10 days prior to her death is properly includable in her gross estate, and the only disagreement turns on whether $ 3,000 per donee is exempted from that value. This question, the parties agree, turns solely on the proper interpretation of section 2035(b)(2), as amended by the Tax Reform Act of 1976, Pub. L. 94-455, 90 Stat. 1520, the Revenue Act of 1978, Pub. L. 95-600, 92 Stat. 2763, and the Technical Corrections Act of 1979, Pub. L. 96-222, 94 Stat. 194 (1980).

Section 2035(a) causes inclusion in a decedent's gross estate of the value of all property transferred by the decedent "during the 3-year period ending on the date of the decedent's death." As amended by the Tax Reform Act of 1976, section 2035(b)(2) (hereinafter the old law) negated the inclusion rule of section 2035(a) with respect to "any gift excludable in computing taxable gifts by reason of section 2503(b) (relating to $ 3,000 annual exclusion for purposes of the gift tax)." ²

1982 U.S. Tax Ct. LEXIS 132">*136 As modified by the Revenue Act of 1978 (hereinafter the new law), ³ however, this subsection applied "to any gift to a donee made during a calendar year if the decedant was not required by section 6019 to file any gift tax return for such year with respect to gifts to such donee."

The scope of the new law is clear: the value of all gifts made within 3 years of the transferor's death is includable in the transferor's gross estate, except for those gifts made to a single 78 T.C. 320">*322 donee which do not aggregate more than $ 3,000 in any calendar year. See secs. 2035(a), 2035(b)(2), 2503(a), and 6019(a). ⁴ The scope of the old law, however, is less clear as to whether it created a per donee annual exclusion of $ 3,000 (the "subtraction out" interpretation) or simply embodied, like the new law, an exception for gifts to a given donee totaling1982 U.S. Tax Ct. LEXIS 132">*137 less than $ 3,000 (the "de minimis" interpretation). There is no question that Congress sought to supplant the ambiguity of the old law with the clarity of the new ⁵1982 U.S. Tax Ct. LEXIS 132">*139 and, in keeping with that objective, provided that, with respect to estates of decedents dying after December 31, 1976, the new law should have retroactive application back to January 1, 1977 (see sec. 702(f)(2), Revenue Act of 1978, supra). As a result, because the (prospective) effective date of the Tax Reform Act of 1976 was also January 1, 1977, the old law is mooted if retroactive application of the Revenue Act of 1978 is given effect. Congress recognized that the retroactive application of the new law could work an injustice upon those who made gifts "in excess of $ 3,000 based upon the assumption that only the excess of the value over $ 3,000 would be included in the gross estate" ⁶78 T.C. 320">*323 (H. Rept. 96-250, at 66 (1979); S. Rept. 96-498, at 87 (1979)), and so, in the Technical Corrections Act of 1979, supra, sec. 107(a)(2)(F), Congress provided that executors could elect the "subtraction out" interpretation in lieu of the "de minimis" interpretation mandated by the Revenue Act of 1978. This election1982 U.S. Tax Ct. LEXIS 132">*138 was only permitted with respect to gifts made in 1977, and thus, by its terms, was not available with respect to gifts made between January 1, 1978, and November 6, 1978. ⁷

1982 U.S. Tax Ct. LEXIS 132">*140 The chronology of the facts of this case places petitioner in the class of persons not entitled to the benefits of the election provided by the Technical Corrections Act of 1979. Petitioner argues that the law in effect when the gifts were made and when the decedent died (the old law) provided a "subtraction out" exemption of $ 3,000 per donee and that the new law constitutes a retroactive abolition of this exemption which violates the due process clause of the Fifth Amendment. Respondent, on the other hand, argues that the old law adopted the "de minimis" concept and that, even if it did not, there is no constitutional infirmity in the retroactive application of the new law. We travel the path to decision conscious of the admonition that Federal statutes should be interpreted to avoid constitutional questions. Califano v. Yamasaki, 442 U.S. 682">442 U.S. 682, 442 U.S. 682">692-693 (1979); Lucas v. Alexander, 279 U.S. 573">279 U.S. 573, 279 U.S. 573">579 (1929).

That, at the time of its enactment, the old law was susceptible of two interpetations cannot seriously be disputed. Its $ 3,000 exemption was tied to section 2503(b), which provided for a $ 3,000 per donee annual1982 U.S. Tax Ct. LEXIS 132">*141 exclusion applicable to all gifts to a given donee whether or not their total exceeded $ 3,000. Thus, the cross-reference in the old law to section 2503(b) supports petitioner's "subtraction out" interpretation. On the other hand, respondent's "de minimis" interpretation 78 T.C. 320">*324 is supported by the old law's applicability being limited to "any gift excludable in computing taxable gifts by reason of section 2503(b)" (emphasis added), for if Congress had intended to enact petitioner's "subtraction out" theory, it would have been better served by a statute which applied to that part of any gift or gifts excludable by reason of section 2503(b).

As we have indicated (see note 5 supra), the legislative history of the old law fails to suggest whether Congress intended to enact a "subtraction out" or a "de minimis" provision. Respondent has not clarified the ambiguity by regulation, and our ability to properly interpret the old law is not helped by the content of the two possibilities, for neither approach is clearly superior to the other. Compare Cremer, "The 1981 Act and Section 2035: Problems and Possibilities," 35 Tax Law. 389, 396-398 (1982) (irrationality of "de1982 U.S. Tax Ct. LEXIS 132">*142 minimis" approach) with H. Rept. 95-700 (see note 7 supra), at 73-74 (unfair administrative burdens imposed on executors by "subtraction out" approach). The only clear fixture on this bare terrain is the statement by the subsequent Congress in the new law that it was "clarifying" the exemption of section 2035(b)(2) to reflect its prior intent. See note 5 supra.

We recognize that "the views of a subsequent Congress form a hazardous basis for inferring the intent of an earlier one," United States v. Price, 361 U.S. 304">361 U.S. 304, 361 U.S. 304">313 (1960). But such views "should not be rejected out of hand as a source which a court may consider in the search for legislative intent," Andrus v. Shell Oil Co., 446 U.S. 657">446 U.S. 657, 446 U.S. 657">666 n. 8 (1980).

while the views of subsequent Congresses cannot override the unmistakable intent of the enacting one, Teamsters v. United States, 431 U.S. 324">431 U.S. 324, 431 U.S. 324">354, n. 39 (1977), such views are entitled to significant weight, NLRB v. Bell Aerospace Co., 416 U.S. 267">416 U.S. 267, 416 U.S. 267">275 (1974), and particularly so when the precise intent of the enacting Congress is obscure. 1982 U.S. Tax Ct. LEXIS 132">*143 [Seatrain Shipbuilding Corp. v. Shell Oil Co., 444 U.S. 572">444 U.S. 572, 444 U.S. 572">596 (1980).]

We are faced in the case at bar with the task of interpreting an ambiguous statute whose meaning simply cannot be discovered by resort to the usual tools. In such circumstances, legislative assistance is entitled to great weight. See Red Lion Broadcasting Co. v. FCC, 395 U.S. 367">395 U.S. 367, 395 U.S. 367">380-381 (1969). This is particularly true when the legislature explicitly characterizes its action as a clarification. See Greensboro Gas Co. v. Commissioner, 30 B.T.A. 1362">30 B.T.A. 1362, 30 B.T.A. 1362">1374-1375 (1934), affd. 79 F.2d 78 T.C. 320">*325 701 (3d Cir. 1935). Indeed, not only is the new law called a clarification of the old law (see note 5 supra), but it was passed in title VII of the Revenue Act of 1978, which was labeled "Technical Corrections of the Tax Reform Act of 1976."

This is not a case where Congress has tried by legislative fiat to change an umambiguous law under the guise of clarification. Cf. United Telecommunications, Inc. v. Commissioner, 65 T.C. 278">65 T.C. 278, 65 T.C. 278">287 (1975), 67 T.C. 760">67 T.C. 760 (1977),1982 U.S. Tax Ct. LEXIS 132">*144 affd. 589 F.2d 1383">589 F.2d 1383 (10th Cir. 1978). We have an instance "Where the original law was subject to very serious doubt," and so, "by permitting subsequent amendments to control the former meaning[,] a great deal of uncertainty in the law is removed. And the legislature is probably in the best position to ascertain the most desirable construction." 2A J. Sutherland, Statutes and Statutory Construction, sec. 49.11, at 265 (Sands 4th ed. 1973). Such an approach is particularly apt where the legislative clarification came on the heels of the passage of the ambiguous statute. Compare 30 B.T.A. 1362">Greensboro Gas Co. v. Commissioner, supra.

Under the circumstances herein, as between the two reasonable interpretations of the old law, we think it appropriate to accept the legislative clarification. Moreover, our interpretation of the old act avoids the constitutional question ⁸ (see p. 323 supra) which petitioner's "subtraction out" interpretation would raise, namely, whether the new law retroactively and unconstitutionally imposed a tax within the ambit of Untermyer v. Anderson, 276 U.S. 440">276 U.S. 440 (1928) -- a case1982 U.S. Tax Ct. LEXIS 132">*145 whose continued vitality has been questioned (see Shanahan v. United States, 447 F.2d 1082">447 F.2d 1082, 447 F.2d 1082">1083 (10th Cir. 1971); Rose v. Commissioner, 55 T.C. 28">55 T.C. 28, 55 T.C. 28">30 (1970)). ⁹

We hold that the old 1982 U.S. Tax Ct. LEXIS 132">*146 law prescribed a "de minimis" exception to the section 2035(a) general inclusion rule, and, 78 T.C. 320">*326 that being the case, petitioner's constitutional argument becomes moot.

Decision will be entered for the respondent.
