“What happened?”

The district court granted the plaintiff’s motion for conditional class certification under the Fair Labor Standards Act. The defendant sought mandamus review, and the Fifth Circuit held the petition in abatement for more information: ” Although there is generally no ‘inflexible rule requiring district courts to file a written order explaining their decisions,” in this case the district court’s ‘lack of explanation makes it impossible for us to determine’ whether mandamus relief would be appropriate here.” In re Schlumberger Tech. Corp., No. 16-20267 (May 13, 2016, unpublished).
