The logic behind this decision is the adoption of specific pay scale system by some autonomous bodies other than BPS e.g. PIA, OGDC etc. However its sheer injustice with the employees of that Autonomous bodies where the same BPS system is being followed. e.g. WAPDA etc. Anyhow the writ can be filed in any court of law by the employees of Autonomous bodies where the BPS structure has been adopted as the case is strong in their favor.
