A state court judge in San Francisco on Friday pushed off a scheduled preliminary approval hearing on a proposed $11 million deal to settle claims that gig-economy company Postmates misclassified couriers who used its mobile delivery app as independent contractors.

In a tentative order issued on the eve of the scheduled hearing, San Francisco Superior Court Judge Anne-Christine Massullo raised more than 30 questions about the terms of the deal and prodded the parties for an estimation of the maximum value of all claims in the case, a figure that was missing in the parties’ proposed settlement.
