Section 2 of Act 31,3 signed into law by Governor Thornburgh on July 22, 1983, purported to raise the basic contribution rate under the Public School Employes’ Retirement Code4 friom 5 1/4% to 6 1/4%. Respondents .seek to have Section 2 of Act 31 constitutionally upheld. We grant petitioners’ motion for summary judgment and deny respondents’ motion for summary judgment for the reasons set forth in AFSCME v. Commonwealth, 80 Pa.
