What penalties apply when a junior uses a restricted technique?

In technical restriction categories:

• First restricted act: no penalty. The referee briefly explains the infringement to the athlete.
• Any later restricted act, whether the same or different: shido, with the referee explaining again.
• Neck and spine actions: if a higher-risk groundwork action is completed by bending the neck or back unnaturally, or by applying a strangle, the penalty is hansoku-make.

If uke is injured by a restricted technique and has to withdraw:

• Pools: the contest is a draw and both athletes can continue in the pool.
• Knockout: the injured athlete is declared the winner. The other athlete can still go into the repechage if there is one.
