When Benchmark Capital Partners sued the former CEO of Uber Technologies Inc. in Delaware Court of Chancery Thursday, the message was clear: One of the ride-hailing innovator’s most powerful investors wants Travis Kalanick off the company’s board.

The filing came amid intense jockeying as Uber’s directors try to name a new chief executive to replace Kalanick, who resigned June 20 after a series of missteps threw the company’s reputation into question. However, Kalanick was able to maintain a board seat in the process, raising concern among some investors that he might yield his voting rights and corporate influence to once again install himself as the head of the company he helped create.
