The clearest legal recognition Santeria has received in the United States came through litigation rather than legislation: after the city of Hialeah, Florida, passed ordinances in 1987 specifically targeting the ritual slaughter of animals practised by santeros, the Church of the Lukumi Babalu Aye challenged the ordinances, and the case reached the United States Supreme Court, which ruled unanimously in 1993 that the ordinances unconstitutionally targeted a specific religion rather than serving any genuinely neutral public health purpose, since the city permitted comparable killing of animals for other reasons while banning it only for this religious use.
The ruling, Church of the Lukumi Babalu Aye v. City of Hialeah, remains one of the most significant modern First Amendment religious liberty decisions in United States law and is taught in law schools well beyond any context specific to Santeria, giving the santero's ritual practice an unusually prominent place in American constitutional law for a tradition that operates with no central church, no seminary and no public register of its priests at all.
A newly initiated santero enters a full year of restriction afterward, the iyaworaje, during which the initiate dresses entirely in white, avoids physical contact with strangers, cannot look directly into a mirror for an extended initial period, and must observe a long list of specific behavioural taboos meant to protect the newly seated orisha while the initiate's own spiritual defences are still forming, a formation period godparents supervise closely and that marks the santero as visibly distinct from other initiates for the whole of that year.
