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.
Step 3. Follow the status quo if the chair has already voted and there is a tie. In order for a vote to pass, more than 50 percent of the votes must be in favor of the motion. If there is a tie, then this requirement is not met and the vote cannot pass.For example, if you have board consisting of eight people including the chair, with four votes in favor and four against, the tie remains and the motion cannot pass.ollow the status quo if the chair has already voted and there is a tie.
