hand, the impugned orders of the authorities, have not been given effect till the stay is vacated and the actual effect of refixation and recovery, are done, after 7 to 8 months, from 31.05.2014. It is a fundamental principle of law of limitation that where the cause of action has not arisen, limitation cannot begin to run. Provisions of the Administrative Tribunals Act 1985, should be construed in conformity with this principle. Even though the orders impugned were issued in the year 2013, cause of action has arisen only when the department started refixing the scale of pay and recovery after 31.05.2014. Starting point of limitation from the date of passing of the impugned orders, issued in the year 2013, must be held to have been postponed till the accrual of cause of action for the petitioners, to challenge the orders, when refixation has been done after 31.05.2014. Right to institute proceedings arises only when an order affecting the rights are infringed. It is not the case of the respondents that the impugned orders of the year 2013, have been communicated to the petitioners even in the year 2013, in which event, it would be appropriate to contend that the period of limitation has to be computed from the date of their knowledge. It is also well settled under the law of limitation, when two or more persons are entitled to institute proceedings in a Court of law, in regard to the same subject matter, each has a distinct cause of action, and thus a distinct period of limitation will apply. Thus, limitation always implies the date of cause of action, for accrual of right to institute proceedings in a Court of law or the forum. In the case on hand, though orders were passed in 2013, they were put on hold, till May 2014. In the absence of proof of notice or communication of the impugned orders or knowledge of the respondents in the year 2013 itself, it cannot be said, their right to challenge had accrued in the year 2013 and that the petitioners have failed to challenge the same, within the prescribed period in the Administrative Tribunals Act 1985.
