Tactics of obstructionism
The most common tactic is the filibuster which consists in extending the debate upon a proposal in order to delay or completely prevent a vote on its passage.
Another form of parliamentary obstruction practised in the United States and other countries is called "slow walking". It specifically refers to the extremely slow speed with which legislators walk to the podium to cast their ballots. For example, in Japan this tactic is known as a "cow walk", and in Hawaii it's known as a "Devil's Gambit". However, slow walking is also used as synonym for obstructionism itself .
