[Margaret Pilkington]

Clause 9 of the 1869 bill of rights(which is still on the statute books) says 'Proceedings in Parliament ought not to be impeached or questioned in any court or any place outside of Parliament'

This was so that the law could not influence the work of Parliament and to prevent interference from judges.

This means that the Supreme Court has exceeded that remit for political reasons.....and this in itself is not lawful.
