We removed a lot of our old pre independence laws in 2006. Most of them were not praciced anyway such as it being illegal for Irish and English to marry or for it to be illegal to speak Irish. Still have plenty of strange ones though.
Jewish people can't own a suit of armour (removed in 2006)
A publican cannot go after a customer who received drink on credit. removed in 2006
A constable may detain any potatoes leaving Northern Ireland ( Still technically active in the North)
The penalty for suicide was death by hanging (repealed 1964)
The Irish were banned from having facial hair (removed in 2006)
We also had a law that made it illegal to place someone in the stocks and pelt rotten tomatoes at them but thankfully it has been repealed in 2005. Yay for the return of pillory!
