After creating a playbook for overturning public teacher tenure rules on one coast, Gibson, Dunn & Crutcher has been sidelined on the other.

On Wednesday lawyers from Gibson Dunn and Kirkland & Ellis were supposed to gather before a judge to learn how closely they’d be collaborating in two separate lawsuits—one filed in Staten Island, and one filed in Albany—challenging New York’s tenure system. Instead, a hearing on consolidating the cases has been postponed, and Gibson Dunn confirmed Tuesday that it is withdrawing from the Staten Island case.
