HOUSE OF LORDS VS. HOUSE OF COMMONS - passing of legislation??

Question

Does legislation have to be approved by both the Upper and Lower Houses (and the Crown) to become law? Which House can introduce which kind of legislation? (or does it matter)?

Also, how many members are there in each House?

Thanks (I have to teach this to someone, but couldn´t find the info in the Britannica or Wikipedia, or better said, couldn´t understand it all.....)

Answer 1

The House of Commons by convention is always the one to put legislation forward.

The House of Lords can refuse to accept it twice.

If that happens, then the Parliament Act can be invoked, which means that the House of Lords is bypassed.

The crown does have to approve all legislation. This is really just a formality: the last time legislation was rejected by the crown was in 1608.

Answer 2

It is the House of Commons who make the laws or "acts of Parliament" but they do not become law until they have been read and agreed by the House of Lords. If the House of Lords do not agree with some or all of the acts [laws] they send it back to the Commons to be changed this can take months or until some sort of agreement can be reached. When both sides agree it is then sent to the Queen for her signature only then does it become law. There are around 650 elected MP.s in the commons and around 200 lords who can discus Government legistration but less than a quarter of them are allowed to vote on Acts of Parliament
