Opinion bt
This is an appeal from the judgment of the Court of Common Pleas No. 5 of Philadelphia County which dismissed an appeal from a decision of the Tax Review Board holding that the appellant was not entitled to use the alternate method of computing Ms mercantile license tax since his operations of converting table but *493 ter into whipped bntter did not constitute manufacturing. 1
A number of years ago an assistant city solicitor made an apparently incorrect ruling in reference to the assessment of the Philadelphia Mercantile License Tax. 2 That ruling has since been repudiated. Appellant now comes before this Court and claims, solely on the basis of this isolated erroneous ruling, that the assessment in his case was discriminatory and infringed upon his constitutional rights of due process and equal protection of the laws.
A taxpayer may not successfully contest his own assessment by offering evidence of an incorrect and repudiated ruling for the absurd purpose of [demanding that the taxing authority again misinterpret the law. As recently as
Commonwealth v. Koppers Co., Inc.,
Judgment affirmed.
Notes
The appellant’s operations clearly do not constitute manufacturing. See
Pittsburgh v. Electric Welding Co.,
Opinion of the City Solicitor, MI/P-27, Ruling 55-23, December 20, 1955, concerning the Petition of Gross Brothers Meat Packers, Inc. There the activities of a meat packer were found to be manufacturing for the purpose of the Philadelphia Mercantile License Tax.
