Rule 4.2 has been updated to introduce the 'casual reserve'.

A 'casual reserve' may be nominated at any position below number 5 in any team without England Squash membership until they have played twice. Their third game requires them to have become at least a 'Just Play' member before the match has been played.

A team captain intending to play a 'casual reserve' in a particular match should email the League Secretary in advance of the match to validate the player.
