Liability for solemnizing illegal marriages

Dear PAO,

I have an estranged husband. A common friend of ours told me that he remarried again. I also discovered that the one who solemnized his second marriage was our pastor. That same pastor knew his prior marriage to me because he solemnized our marriage, but he still solemnized my husband's second marriage to a different woman. Is there a liability for solemnizing an illegal marriage ceremony?
