Official Board of Trade report to the Privy Council's Committee for Plantation Affairs, dated 24 June 1760, reviewing 19 acts passed by the Pennsylvania Assembly in 1758-1759. The report examines objections raised by the Penn Proprietors to 11 of these acts, including debates over proprietary rights, crown prerogative, judicial tenure, taxation, and legislative authority. Includes extensive legal argumentation on the limits of provincial law-making and the Crown's supervisory power. Contextually relevant to Isle of Man Revestment as a parallel case of colonial constitutional negotiation and proprietary-vs-parliamentary authority disputes.
