Colorado and English Common-Law?
A 15-year-old girl can enter into a common-law marriage in Colorado, and younger girls and boys possibly can, too, a state appeals court ruled Thursday.
While the three-judge panel stopped short of setting a specific minimum age for such marriages, it said they could be legal for girls at 12 and boys at 14 under English common law, which Colorado recognizes.
I don't really think that states of the US should be using English common law, if that common law is making such distinctions between girls and boys. Extremely, extremely wrong. Not to mention completely bizarre.
