Two months into a contentious discovery process between Twitter and Elon Musk, Chancellor Kathaleen McCormick has brought in a special master to resolve two lingering disputes and decided Twitter doesn’t have to turn over more documents related to its user metrics.

An order issued Friday named Christopher Sontchi, a former District of Delaware bankruptcy judge now at Delaware ADR, as a special discovery master assigned to determine whether either side will need to hand over documents they say are privileged. In another order, McCormick resolved the last piece of a discovery motion from Musk that was argued at a hearing Tuesday.
