If a point has commenced and a team does not have exactly seven (7) people playing the point, or does not have the correct gender ratio, then the opposition may call a violation and stop play, or the infringing team may use a time-out to address the issue (as per Rule 20.4).
The infringing team must choose which of their player(s) will be removed/added. If players are being added, the opposition may make the same number of substitutions to their team.
