How are Bill Committees ineffective?

-Government Whips completely dominate the Proceedings, having an Absolute Majority and the votes being whipped. 99% of Ministerial Amendments succeeds, while 1% succeeds for Non-Government Amendments. -Bill Committees are involved after Parliament has voted on it. The Legislation seems to be a done deal at that Point -Bill Committees may lack Expertise because it is Temporary and Controlled by Party Whips. Party Whips play a key role in choosing who is allowed to Sit on these Committees so can chose Loyal Government MPs
