A Delaware Court of Chancery judge on Thursday set an Aug. 30 hearing date for Travis Kalanick’s motion to dismiss an investor lawsuit seeking to oust him from the Uber Technologies Inc.’s board, as Benchmark Capital Partners continued to step up its attack on the ride-hailing company’s ousted CEO.

In a court filing, Benchmark called Kalanick’s response to the lawsuit “facile,” and said Kalanick had done nothing to refute allegations that he had misled Uber investors in order to secure control over three new seats in 2016.
