3.1. The first submission of learned Sr. Advocate appearing for the petitioner that his client’s deputation period could not have been unilaterally cut-short eventually repatriating him to the parent department when the respondent-Corporation itself had requested for continuation of service, is unsustainable, cannot be countenanced. Ordinarily, deputation is a tripartite arrangement: it involves lending department, borrowing department and the employee concerned, unless the rules otherwise provide. Admittedly, the deputation period having expired as pointed out in the order dated 29.05.2024 itself, none has a right to seek continuation nor to challenge determination of deputation by efflux of time. In the absence of legal right, no writ petition is maintainable, whatever be the arguable infirmity in the Tribunal’s judgment.
