"7. To summarise, normally, a belated service related claim will be rejected on the ground of delay and laches (where remedy is sought by filing a writ petition) or limitation (where remedy is sought by an application to the Administrative Tribunal). One of the exceptions to the said rule is cases relating to a continuing wrong. Where a service related claim is based on a continuing wrong, relief can be granted even if there is a long delay in seeking remedy, with reference to the date on which the continuing wrong commenced, if such continuing wrong creates a continuing source of injury. But there is an exception to the exception. If the grievance is in respect of any order or administrative decision which related to or affected several others also, and if the re-opening of the issue would affect the settled rights of third parties, then the claim will not be entertained. For example, if the issue relates to payment or refixation of pay or pension, relief may be granted in spite of delay as it does not affect the rights of third parties. But if the claim involved issues relating to seniority or promotion, etc., affecting others, delay would render the claim stale and doctrine of laches/limitation will be applied. Insofar as the consequential relief of recovery of arrears for a past period, the principles relating to recurring/successive wrongs will apply. As a consequence, the High Courts will restrict the consequential relief relating to arrears normally to a period of three years prior to the date of filing of the writ petition.
