The Criminal Procedure Act 1851 (14 & 15 Vict c 100) is an Act of the Parliament of the United Kingdom. It was drafted by Charles Sprengel Greaves. Stephen said that compared to earlier legislation on defects in indictments, the Criminal Procedure Act 1851 "went further in the way of removing technicalities, but it did so by an enumeration of them, so technical and minute, that no one could possibly understand it who had not first acquainted himself with all the technicalities which it was meant to abolish."
