Ministry of Defence v. Prabhash Chandra Mirdha, (2012) 11 SCC 565 : (2013) 1 SCC (L&S) 121 : 2012 SCC OnLine SC 466 at page 572
10. Ordinarily a writ application does not lie against a charge-sheet or show-cause notice for the reason that it does not give rise to any cause of action. It does not amount to an adverse order which affects the right of any party unless the same has been issued by a person having no jurisdiction/competence to do so. A writ lies when some right of a party is infringed. In fact, charge-sheet does not infringe the right of a party. It is only when a final order imposing the punishment or otherwise adversely affecting a party is passed, it may have a grievance and cause of action. Thus, a charge-sheet or show-cause notice in disciplinary proceedings should not ordinarily be quashed by the court. (Vide State of U.P. v.
