Appeals Committee. Disputed situations in tournaments.

Probably, it is primarily needed by those who need it.

A recent poll showed that the Appeals Committee (AK) is needed by many, and the constant whining of a few disgruntled people doesn't count. It is incorrect to use the club tournament as an example – the AK is not needed there, everything is already visible.

In the WT chat, the phrase "complain to the AK" is close in meaning to being sent on a long walk.

The WT chat is generally a garbage dump; it is often unpleasant to read, even for me.
