What follows is an opinion from a United States Court of Appeals.
Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the first listed appellant. The nature of this litigant falls into the category "natural person (excludes persons named in their official capacity or who appear because of a role in a private organization)". Your task is to determine the gender of this litigant. Use names to classify the party's sex only if there is little ambiguity (e.g., the sex of "Chris" should be coded as "not ascertained").

Opinion:
HAAG v. COMMISSIONER OF INTERNAL REVENUE.
No. 4679.
Circuit Court of Appeals, Seventh Circuit.
June 7, 1932.
Respondent assessed a deficiency tax of $1,811.18 against petitioner for the year 1922. On appeal" this amount was reduced to $1,570.57 by the Board of Tax Appeals. Petitioner disputes the valid assessment of any deficiency tax. . „
Petitioner’s income tax return for the year 1922 showed $2,445.45 as ineome received from the partnership of the Haag Drug Company. Respondent increased this amount to $13,083.80, fixed petitioner’s net ineome at $24,156.45, and assessed a deficiency tax of $1,811.18. The Board reduced the amount of ineome and also the tax thereon. The present controversy is over the propriety of including ineome from this partnership as part of petitioner’s ineome.
The Haag Drug Company was a partnership with. Julius A. Haag and Louis E. Haag, brothers, each owning a one-half interest. On May 16, 1922, Julius Haag died. He bequeathed one-half of his property to petitioner and the other one-half to his partner. His will was promptly probated, and petitioner and her brother became executors and administered the estate. The brother died June 7, 1923, before the administration of the estate was completed. The business of the Haag Drug Company, after the death of Julius, was conducted by the brother Louis, under orders of the Probate Court, until he died. The Commissioner determined the net ineome of the Haag Drug Company for the year 1922 to be $83,736.86. The Board reduced this sum by $9,000. The Board included one-fourth of income for 7% months, or $11,677.63, in petitioner’s 1922 income and computed the deficiency tax at the above stated sum of $1,570.57. Petitioner’s attack upon the inclusion of this item is predicated npon her assertion that she was not a partner of the Haag Drug Company.

Before ALSCHÜLER, EVANS, and SPARKS, Circuit Judges.
EVANS, Circuit Judge
(after stating the facts as above).
The precise question presented by the record before us may bo stated thus: Should the petitioner be chargeable with the tax duo upon the Julius Haag share of the net income of the Haag Drug Company earned in 1922, after tiro death of Julius? No question is involved as to the correctness of the amount of the Haag Drug Company’s net income for 1922, nor is it denied that a tax was due the Government thereon.
Petitioner contends that she never was a member of the copartnership of Haag Drug Company and was not chargeable with the tax on one-halt' of the income of said company earned in 1922, after Julius’s death. Respondent meets these contentions by asserting (a) that petitioner is estopped to deny membership in the partnership and (b) that she has failed to show that she was not a member of the partnership during 1922, after her brother died.
Estoppel. Petitioner’s return for the year 1922, was filed ten months after the death of Julius Haag. In this return petitioner listed $2,445.45 as income from the partnership of Haag Drag Company, 114 North Pennsylvania Street, Indianapolis, Indiana. The Haag Drag Company made a partnership return listing petitioner and giving her address under the heading- “Name and Address of each Partner.” Her interest was stated to be one-fourth for seven and one-half months. Both the petitioner and the partnership made like representations in their income tax returns for the year 1923. Respondent accepted this statement of petitioner’s status as a member of the partnership and confined its investigation to the correctness of the earnings of the partnership for the year 1922. The determination was made February 19, 1927. Not until this determination was made did petitioner deny membership in tlie partnership. In the meantime the period of limitation for assessment and collection of the 1922 taxes had expired, and it was too late for respondent to assess tlie tax against the estate.
Both precedent and the principles underlying the doctrine of estoppel support respondent’s position. Rockwood v. United States (Ct. Cl.) 38 F.(2d) 707; McDonald Coal Co. v. Heiner (D. C.) 9 F.(2d) 992, affirmed McDonald Coal Co. v. Lewellyn (C. C. A.) 16 F.(2d) 274; Illinois Central R. R. Co. v. Commonwealth, 128 Ky. 268, 108 S. W. 245, affirmed 218 U. S. 551, 31 S. Ct. 95, 54 L. Ed. 1147; Union School District v. Bishop, 76 Conn. 695, 58 A. 13, 66 L. R. A. 989; Central Pacific Railroad v. California, 162 U. S. 91, 16 S. Ct. 766, 40 L. Ed. 903.
Having represented under oath to the Government that she was a member of the partnership and the Government having accepted her representation and acted accordingly, she can not be heard to deny that status after the time had passed for the Government to validly assess a tax against the estate. The soundness of this conclusion is fortified by the additional reason that, had a tax been assessed against the estate of the deceased brother, a part of the tax, equal to what petitioner must now pay, would have ultimately been deducted from her share of said estate.
The order of the Board of Tax Appeals is affirmed.
