The Town Board has appointed attorney Kelly A. Stewart of Burnt Hills to fill a vacancy created by the recent resignation of Jeremy Knight.
The board appointed Stewart in a 3-1 vote Thursday, with the board's three Republicans voting in favor and town Supervisor Patti Southworth, an independent, voting against.
The appointment gives the board, which has frequently been split 3-2 in recent years, a fourth Republican.
Knight was a Democrat who generally voted with Southworth.
"My vote was not against Ms. Stewart , it was against the process for deciding who the new Town Board member would be," Southworth said.
She said she had no input as the Republicans picked Stewart .
Stewart was selected from among five candidates at a Republican caucus, said board member Tim Szczepaniak, who supported her.
Knight, who was first elected in 2009, resigned in September, citing the need to spend more time with the family business, Knight Orchards.
Stewart has worked for 19 years for the state Legislative Bill Drafting Commission, where she researches, drafts and edits legislative proposals for the state Legislature.
She also provides legal counsel to a family-run business, Stewart Construction.
She is a graduate of Colgate University and Albany Law School. She has served on the Ballston Community Library board and is its president.
Stewart has also been a member of the Stevens and O'Rourke school PTAs, coached recreational soccer and served as commissioner of Pop Warner Football and team manager in Burnt Hills-Ballston Lake junior baseball.
Stewart has lived in Ballston since 1996. She is married to Todd Stewart , and they have three children.
The three Republican members said in a statement Friday that Stewart has a "unique combination of community involvement and extensive background that will be a great asset to the Town Board and will serve the Ballston residents well."
The appointment will be through the end of 2013, at a salary of $8,190.
There will be an election to fill the seat in November 2013.
