“Yikes” was Michael Reagan’s reaction to the news that Gov. Jerry Brown on Friday signed legislation allowing more than two people to be listed as a child’s parents. The Sacramento Bee reports:

Senate Bill 274 authorizes a court to recognize more than two parents if endorsing fewer would be “detrimental” to the child.

[Sen. Mark] Leno’s measure grew out of an appellate court case involving a biological mother, her same-sex partner and a man who had an affair with the mother while she was temporarily separated from her female lover. In the 2011 case, the California Court of Appeal held that courts could not recognize more than two parents even if doing so would protect the child from harm.

Leno said in an interview that he expected the law to be used “sparingly.”
