Task: songer_casetyp1_7-2

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "economic activity and regulation". 

PER CURIAM:
In this second go around Taxpayer asserts that brokerage and related expenditures in the purchase of securities are not to be added to the price paid to the seller but should be deducted as an expense. Similarly, he argues that such costs of sale are not to be deducted from the sales proceeds from the buyer. Despite the earnestness of his contentions they come too late. For the law has held to the contrary. Woodward v. Commissioner, 1970, 397 U.S. 572, 574—75, 90 S.Ct. 1302, 1304, 25 L.Ed.2d 577, 581; Spreckles v.
