APPEAL ====== This appeal comprises three separate issues: 1) Whether the Superior Court erred in according to the Board statutory authority to prohibit do-it-yourself plumbing. 2) Whether the Superior Court erred in adjudicating this controversy in the absence of any and all legally valid evidence. 3) Whether the Superior Court erred in entertaining and allowing a Cross-Motion from an entity that was not legally a party to the action; and whether the Superior Court erred in imputing to the defendant the State Plumbing Board concurrence in a motion where such concurrence is not documented in the record, and where the State Plumbing Board had failed to oppose the Do-It-Yourself plumber's motions. These three issues have as their common denominator to what extent, if at all the Commonwealth has sovereign immunity for conduct proscribed to its citizens.
