1. What is sought for in all these Writ Petitions is a declaration, declaring that the impugned order of the first respondent in G.O.Ms.No.402, Higher Education (H2) Department, dated 13.12.2006, in so far as it seeks to amend the service conditions of the University employees of the second respondent University, is ultra vires to the provisions of the second respondents' Universities Acts, particularly the provisions relating to Regulation of Service Conditions of the Staff of Universities, and without competence of executive power of the first respondent under Article 162 of the Constitution of India.
