The DOJ announced on Friday, June 16, 2017, that it was reversing its position on the validity of class action waivers in arbitration agreements and would file an amicus brief in support of the employer's position in NLRB v. Murphy Oil. I get that a change in administration can bring with it a change in policy, but this is unfortunate in that it overtly politicizes a legal analysis that should at least attempt to be a textual analysis that doesn't depend on which way the wind blows. I suppose Judge Posner has the right of it when he argues that all the supposedly dispassionate judicial reasoning is just a veneer over personal preference and wanting anything as significant as this issue to be decided apolitically is laughably naive. Still, I think the better approach for the DOJ would have been to undertake the equivalent of a noisy withdrawal, officially retracting its position and choosing to take a neutral position in the case.
