Since the 2012-13 season, referees have reviewed all block/charge calls when they are not reasonably certain as to whether the defender was inside or outside of the restricted area. For more information about what constitutes a block or a charge. Restricted area replays are conducted only during the last two minutes of the fourth period and during all of overtime.
When conducting their review, referees attempt to confirm or overturn their original call.
The call is deemed a block if referees deem the defender was:
- Not in a legal guarding position, or
- In a legal guarding position, but inside the restricted area
- The call is deemed a charge if the defender was in a legal guarding position and outside the restricted area.
- Referees also determine if any unsportsmanlike acts or unnecessary contact occurred.
