Manhattan Surrogate Nora S. Anderson and a co-defendant, Seth Rubenstein, were acquitted yesterday in a verdict that could blow a hole in the contribution limits under the state’s campaign finance law.

After deliberating for about eight hours over two days, the jury found that the prosecution had failed to prove beyond a reasonable doubt that the judge and Mr. Rubenstein had lied in campaign filings about $250,000 pumped into her 2008 primary campaign for Manhattan surrogate.
