How does the play-the-ball and dummy-half work?

Question

Accepted Answer

Markers must remain passive and must not move until the first receiver has received the ball or the dummy-half has started to run. All other defenders must retire a minimum of five metres at the play-the-ball. The dummy-half may run with the ball or pass. If tackled in possession, the ball is handed over and a scrum is formed. The dummy-half may not run and score. The ball shall not be stolen from the ball-carrier at all.
