In California, a bill to set the minimum marriage age at 18 — the state’s age of consent — failed in 2017 after objections from lawmakers and liberal groups such as the state’s American Civil Liberties Union. The state currently has no minimum marriage age and collects little to no data on child marriages.

The ACLU argued that the bill “unnecessarily and unduly intrudes on the fundamental rights of marriage without sufficient cause,” adding that “largely banning marriage under 18, before we have evidence regarding the nature and severity of the problem, however, puts the cart before the horse.”

Other groups, like Planned Parenthood and The National Center for Youth Law, a youth advocacy organization, agreed.
