 - 11e2+) [ADDITION] If an extra attempt itself leads to an additional extra attempt, the competitor should keep doing extra attempts until there is a valid extra attempt to replace the original regularly numbered attempt.

The competitor should do extra attempts until there is a valid extra attempt to replace #2. Suppose later another attempt leads to extra attempts, the competitor should proceed in a similar way as for #2.

 - 11g) The WCA Delegate must ensure that copies of the Regulations and Guidelines are available (e.g. printed, digital, or accessible via internet) to officials and competitors for consultation on any incidents.
 - 11h) A WCA Delegate may require competitors in serious violation of [Regulation 2k3](regulations:regulation:2k3) to leave the competition venue, taking into account the seriousness of the situation and the best possible course of action. If the competitor refuses to do so, they may face disciplinary action in the WCA.

+    - 11i1) In the following cases, an extra attempt must be granted to replace the affected attempt. If no extra attempt is granted, the result will be considered DNS:

Exception: the WCA Delegate may grant an extra attempt at their discretion if they believe this provides a significantly fairer outcome (e.g. the incorrect scramble received was extremely easy and the competitor achieved a new personal record, the incorrect scramble impacted the podium for an event, or the puzzle was deliberately scrambled incorrectly).

A competitor should not be penalized for incorrectly reporting a duplicate scramble genuinely, at the discretion of the WCA Delegate.
+    - 11j2) If the error is noticed during the group, the WCA Delegate should make an effort to give the competitor the correct scramble. An extra attempt may be given if the WCA Delegate is not certain what the correct scramble should be.
