Maine v. Taylor

Maine v. Taylor, 477 U.S. 131 (1986), was a case in which the Supreme Court of the United States held that there was an exception to the "virtually per se rule of invalidity" of the dormant commerce clause.^[1] The Supreme Court of the United States found that a Maine law prohibiting the importation of out-of-state bait fish was constitutional because Maine authorities couldn't be certain that imported fish would be free of "parasites and nonnative species" that might pose environmental harm to local ecology. Discriminatory laws may be upheld only if they serve "legitimate local purposes that could not adequately be served by available nondiscriminatory alternatives," wrote Justice Blackmun, author of the majority opinion. In City of Philadelphia v. New Jersey, the Court had previously ruled that New Jersey's ban of out-of-state solid waste was facially discriminatory to the state's residents in a national market and was therefore overturned.^[2]
