It is named from the main item of business which was a statute - the Suppression of Heresy Act - passed for the suppression of the Lollards,
that whoever should read the Scriptures in English, which was then called Wicliffe's Learning, should forfeit land, cattle, goods, and life, and be condemned as heretics to God, enemies to the crown, and traitors to the kingdom; that they should not have the benefit of any sanctuary, though this was a privilege then granted to the most notorious malefactors; and that, if they continued obstinate, or relapsed after pardon, they should first be hanged for treason against the king, and then burned for heresy against God.
The Parliament also confirmed Archbishop Arundel's policy of licensing books for publication:
no book ... be from henceforth read ... within our province of Canterbury aforesaid, except the same be first examined by the University of Oxford or Cambridge ... and ... expressly approved and allowed by us or our successors, and in the name and authority of the university ... delivered unto the stationers to be copied out.
The king received the rights to “Tonnage and Poundage” for life from this Parliament. This precedent was continued for all Monarchs until the Useless Parliament in 1625 when Charles I was granted the right for only one year.
