According to Minnesota Public Radio:
The congregation will continue to hold both opposite-sex and same-sex weddings at its meeting house, but will no longer sign the legal marriage certificate for opposite-sex couples. Instead, couples will need to have the certificate signed by a justice of the peace.
Quacker congregations have no formal clergy, and like many anabaptist type groups are peer to peer. Generally they are liberal both theologically and socially although this isn't always true. I think this is a courageous action and a good way for them to protest the injustice of unequal marriage laws.
