Dickstein Shapiro won't be merging with Bryan Cave, according to an attorney at the law firm and two sources outside of the firm with knowledge of its recent discussions.

The potential merger fell through in the past few days, following a vote by Dickstein Shapiro partners on Dec. 14 to approve a tie-up, the sources said.

Bryan Cave partners had been prepared to vote on the merger two weeks ago. But Bloomberg Big Law Business reported on Monday that the Bryan Cave/Dickstein Shapiro merger may have “hit a snag” because Bryan Cave leaders wanted certain Dickstein Shapiro partners to commit to working at the new firm for longer than they would agree.
