The judge who officiated over the first King County same-sex marriage in December 2012 will now take a seat on the State Supreme Court.

Gov. Inslee announced Thursday Mary Wu was sworn in to replace retiring Justice James Johnson, who left his post due to health-related reasons.

She was appointed to the King County Superior Court by former Governor Gary Locke,  and is the first such appointee by Gov. Inslee.

While she is finishing the term vacated by Justice Johnson, she will be running for election to keep the position in November.  Johnson's term expired this year.

Shortly after Washington state's same sex marriage law went into effect, Justice Wu officiated over the very first same-sex marriage that took place in King County, shortly after midnight December 9th, 2012.
