Justice, we do not believe that the very first act extended terms at all. Speaking technically, which for a lawyer means speaking accurately, the 1790 act did not extend a Federal term. The 1790 act granted a term for works that already existed in precisely the pattern that the English parliament had done in the Statute of Anne in 1710, and that the English parliament did with monopolies, general monopolies in the statute.
Justice was an act that extended terms
The statement is correct because it is not clear whether the 1790 act in question is the Justice act or not. the first statement also states that Justice may not have been the very first act extended terms. This makes it rather ambiguous.
