Instrukcje dla litewskich komisarzy skarbowych delegowanych na sejmy (1780–1790)

Five instructions prepared by the Treasury Commission of the Grand Duchy of Lithuania were published. This Commission, founded in 1764, consisted of two Lithuanian treasurers, and varying number of commissioners elected by the parliament. The Commission functioned as a court and administrative organ in charge of managing state finances. It was part of the executive, due to which fact it was answerable to the parliament (the Sejm of the Polish-Lithuanian Commonwealth). Every two years, the Commission delegated two commissioners for convened Sejm sessions. During parliamentary control of the Commission these Commissioners were present to provide information for members of the parliament. The first instruction that the Commissioners prepared was in 1780, during the affair concerning treasurer Antoni Tyzenhauz. He was accused of financial abuse, and the Commission tried to convince the members of the parliament, that Tyzenhauz alone was responsible for these crimes. Subsequent to this first one, instructions (1782, 1786, 1788, and 1790) contain reform proposals. The Treasury Commission described practical problems and possible solutions, suggested changes to tax structures, issued new legal regulations, and reorganized rules of operation in the institution.
