SAN FRANCISCO — A San Jose arbitrator vindicated a team of East Bay attorneys this week, dismissing a former client’s malpractice accusations as mere Monday morning quarterbacking.

The Walsh Law Firm and Ramsey Law Group, two small firms based in Lafayette, Calif., are entitled to $260,000 for their work representing CrestPoint Solutions Inc., wrote retired Santa Clara Judge Read Ambler, a JAMS neutral. CrestPoint’s CEO had refused to pay, saying the attorneys did not consult him before agreeing to a paltry settlement in the company’s case against AT&T.
