Actually in 1990, I wrote to the then Home Secretary suggesting that they put in a clause to the Criminal Justice Bill, removing those laws from the Statute book, suggesting that nobody would seriously oppose them.
The reply I got was that after the restoration of the monarchy, the parliament that Oliver Cromwell lead and their laws were not recognised and so those laws which he promulgated were not considered to be on the statute book.
I wonder which poor civil servant had to track that one down
So it is a matter of dispute if his laws are valid, I would like to see what other historians say about that matter
