1. The petitioners in the present writ petition are mechanics working in respondents’ Corporation, i.e., Andhra Pradesh State Road Transport Corporation (APSRTC). They have filed the present writ petition questioning the action of the respondent Corporation as illegal, unjust and arbitrary in not granting the selection grade scale stagnation increments to them on completion of 12 years of service.

All the petitioners have completed 12 years of service.
