Equal Protection Clause - Suspect Classifications

Suspect Classifications

The Supreme Court has seemed unwilling to extend full "suspect classification" status (i.e., status that makes a law that categorizes on that basis suspect, and therefore deserving of greater judicial scrutiny) to groups other than racial minorities and religious groups. In City of Cleburne v. Cleburne Living Center, Inc. (1985), the Court refused to make the developmentally disabled a suspect class. Many commentators have noted, however—and Justice Marshall so notes in his partial concurrence—that the Court does appear to examine the City of Cleburne's denial of a permit to a group home for mentally retarded people with a significantly higher degree of scrutiny than is typically associated with the rational-basis test.

In Lawrence v. Texas (2003), the Court struck down a Texas statute prohibiting homosexual sodomy on substantive due process grounds. In Justice Sandra Day O'Connor's opinion concurring in the judgment, however, she argued that by prohibiting only homosexual sodomy, and not heterosexual sodomy as well, Texas's statute did not meet rational-basis review under the Equal Protection Clause; her opinion prominently cited City of Cleburne.

Notably, O'Connor did not claim to apply a higher level of scrutiny than mere rational basis, and the Court has not extended suspect-class status to sexual orientation. Much as in City of Cleburne, though, the Court's decision in Romer v. Evans (1996), on which O'Connor also relied in her Lawrence opinion, and which struck down a Colorado constitutional amendment aimed at denying homosexuals "minority status, quota preferences, protected status or claim of discrimination," seemed to employ a markedly higher level of scrutiny than the nominally applied rational-basis test. While the courts have applied rational-basis scrutiny to classifications based on sexual orientation, it has been argued that discrimination based on sex should be interpreted to include discrimination based on sexual orientation, in which case intermediate scrutiny could apply to gay rights cases.

The court has also refused to view government discrimination based on a citizen's political belief or affiliation to be a suspect class.
