In Sushil Kumar Sharma v. Union of India, (2005) 6 SCC at page 285 this Hon'ble Court has held that:
12. It is well settled that mere possibility of abuse of a provision of law does not per se invalidate a legislation. It must be presumed, unless the contrary is proved, that administration and application of a particular law would be done “not with an evil eye and unequal hand”. (See A. Thangal Kunju Musaliar v. M. Venkatichalam Potti [(1955) 2 SCR 1196 : AIR 1956 SC 246)
