Even that is a matter of opinion and interpretation, just that of a judge, which can be influenced depending on how good the lawyer is. Besides that, laws don't matter if they can't be enforced. No baby to perform DNA tests on = good luck proving any 2 people (related or not) fucked, unless it was in public or something. It's probably partially why sibling incest is still legal in Ohio, at least in part, damned near impossible to enforce without putting 24/7 surveillance in every room of every house anyway (intergenerational incest is still illegal but more common than you may think, people just keep it in the closet like most homos did in the 1950's and before, the few prosecutions that have ever happened had accidental babies used as Exhibit A after they were DNA tested, or where one of the couple went to the cops after a bad breakup and cried rape for payback reasons).
