Permission is required if you plan to extend or alter the roof space more than specified limits and conditions: 1  Volume increase of 40 cubic metres for terraced houses or 50 cubic metres for detached & semi-detached houses.

The rules haven't changed in a few decades, but the customs have. In both houses of Congress, you still need a majority (50%+1) to pass a bill. In the House of Representatives, that's the only consideration. In the Senate, the rules are a bit more complex. If the bill makes it to a vote, it needs only 51 votes. But you need to debate before it gets to a vote.
The process has a number of specific steps. If the bill makes it through all the steps in the chamber in which it was introduced (the first house), it goes to the other chamber (or second house) and goes through the same steps there. Each step is identified and explained below.Bills must have three readings in each house in order to pass the Legislature.) Leadership determines to which committees bills will be referred; this is usually determined by the bill's subject matter. Bills that require an appropriation or that raise revenue must also go to a fiscal committee for review.
