Double Movement

Hi can you clarify double movement laws please

I thought you were allowed to make a positive movement post tackle

Hi Simon

The words "double movement" do not appear anywhere in the laws of the game.
Following a tackle the ball carrier has to  pass, place or release the ball "immediately". (Law 15.5).

There is one exception.  A ball carrier tackled close to the try line may reach out and ground the ball to score, but again this must be done "immediately".

Double movement is a phrase usually used to describe the actions of a ball carrier who scrabbles along on his hands and knees, or lurches forward using his knees and elbows, after having been tackled.  This kind of action is penalised as "not releasing the ball immediately after a tackle".
