East League rules require that all umpires officiating in East League matches are registered with a County Umpiring Association. Teams that use unregistered umpires are likely to be penalised. Full details of this rule can be found at: http://www.east-leagues.co.uk/leagues/leaguerulesCurrent.htm
Umpires registered with Cambridgeshire Umpiring Association are covered by a third party liability insurance policy, limited to £6m. Under the terms of the policy umpires are advised to record details of any incident in which a player receives a serious injury and to pass the details to the Level One Coordinator.
