 As solicitor general, Castor was empowered to make all final legal decisions of the Office of Attorney General and in all other respects operate as "the most senior deputy attorney general of the Commonwealth" according to the order creating the position.The move was necessitated because the Attorney General had her license to practice law suspended by the Pennsylvania Supreme Court.Castor was supposedly subordinate to Kane in all matters except for making legal decisions on behalf of Pennsylvania, though most observers considered him the de facto attorney general, a fact later confirmed upon Kane's resignation.
