(Treason had been brought in line with felony in 1945.) The 1967 Act abolished felonies and stated that all former felonies would be tried according to the rules of procedure and evidence that applied in trials and pre-trial hearings for misdemeanours, whether the felony had been committed before or after the Act was passed.
Prior to 1945, treason was classified as a felony. The 1967 legislation abolished this classification, instead stipulating that all former felonies would be prosecuted under the rules and evidence used for misdemeanors, regardless of when the crime was committed.
