[The San Francisco 2004 same-sex weddings took place between February 12 and March 11, 2004](https://en.wikipedia.org/wiki/San_Francisco_2004_same-sex_weddings), and were then “voided” on August 12, 2004.


But OBERGEFELL v. HODGES voids the voiding...


Could these couples have been prosecuted for filing single for tax years 2004-2014?



Were there retroactive changes to CA marriage laws about same-sex couples?
