A federal judge in Newark has refused, at least for now, to compel arbitration of a wage-and-hour class action suit against Santander Bank N.A., finding that language in the company’s arbitration agreement with mortgage loan officers is ambiguous.

The agreement, signed by plaintiffs in the case, is rendered ambiguous by a clause indicating the employee has received a description of the company’s commission plan for mortgage officers, U.S. District Judge Madeline Cox Arleo of the District of New Jersey ruled in Ranieri v. Banco Santander S.A.
