Petitions in parliament are "parliamentary proceedings" in accordance with the Bill of Rights 1688.
The Bill of Rights states (in Article 9):
"That the freedom of speech and debates or proceedings in Parliament ought not to be impeached or questioned in any court or place out of Parliament".
What this means is the a parliamentary petition cannot be gagged by the courts. It can only be controlled by the rules in parliament.
The wording of parliamentary petitions, however, is complex. Anyone wishing to present a petition should liaise with an MPs office about the wording.
