HARRISBURG — Republican Gov. Tom Corbett said Thursday it was inappropriate for his lawyers to include a reference to children in a legal brief involving same-sex couples seeking marriage licenses.

Corbett’s administration has filed a lawsuit seeking to block same-sex marriage licenses in suburban Philadelphia, where Montgomery County Register of Wills D. Bruce Hanes has issued more than 150 to gay couples since July 24.

State attorneys said in a court filing Wednesday that same-sex couples seeking to intervene in the state’s lawsuit should be blocked from doing so because they had no legal right to marry in the first place. The lawyers then made an analogy to a pair of 12-year-olds, saying if the children were issued a marriage license and tried to defend it in court, they wouldn’t be taken seriously because the license was never valid.

Corbett released a statement Thursday calling it a poor analogy.

“The case involving Montgomery County revolves around a very basic question: Does a public official have the authority to disregard state law based on his own personal legal opinion about the constitutionality of a statute?” he said.

Equality Pennsylvania issued a statement taking Corbett’s lawyers to task over the legal argument.

“If there is one thing we can all agree on, it’s that all people deserve to be treated with respect,” said the group’s executive director, Ted Martin.
