Virginia authorities have decided not to prosecute a former gubernatorial aide or his ex-girlfriend on misdemeanor assault charges stemming from their troubled relationship.

Eric Finkbeiner, a former aide to three Virginia governors and current lobbyist for the Washington Redskins, had faced four charges of misdemeanor assault and three charges of violation of a protective order. His ex-girlfriend, Summer D. Hudson, faced three assault charges.

Prosecutors agreed not to pursue the case after Finkbeiner and Hudson indicated in Chesterfield General District Court on Thursday that they would refuse to testify, invoking their Fifth Amendment rights against forced self-incrimination. Substitute Judge James Mathews ordered the two to stay away from each other, threatening to fine them both $15,000 if they failed to do so.

“Everybody was admonished by the judge and he put both parties under a $15,000 peace bond, and said, basically, ‘Go and sin no more, and I don’t want to see ya’ll,’ ” said attorney George Edwards, who represented Hudson.

Todd Stone, who represented Finkbeiner, did not immediately respond to a request for comment.

The resolution of the case was first reported by the Richmond-Times Dispatch.

Finkbeiner is a lawyer who served governors Robert F. McDonnell (R), George Allen (R) and Douglas Wilder (D). He served as a senior policy adviser to McDonnell before leaving to join the law firm McGuireWoods in May 2011. He works as a lobbyist, representing the Redskins, helping to negotiate a deal last year to bring the team’s training camp to Richmond.
