I don't support this kind of detention, but the case reads like he overstayed his original conditions of entry.
According to the court order, he entered the US on the Visa Waiver Program in 2009. He may have a work permit now because anyone can file for an Employment Authorization Document (EAD) through an I-765 while they are applying for a green card through marriage, but there's no indication that he had work permits before that. I've encountered Irish people throughout the US in similar situations.
