The language used in the suit indicates Benchmark, which owns 13 percent of Uber’s shares after an early investment, is taking a hard line against Kalanick, who was forced to resign in June following a shareholder revolt:

“Kalanick, the former CEO of Uber, to entrench himself on Uber’s Board of Directors and increase his power over Uber for his own selfish ends. Kalanick’s overarching objective is to pack Uber’s Board with loyal allies in an effort to insulate his prior conduct from scrutiny and clear the path for his eventual return as CEO — all to the detriment of Uber’s stockholders, employees, driver-partners, and customers.”

In particular, the lawsuit concerns a decision in June 2016 to expand Uber’s board from eight to 11, giving Kalanick the right to choose those seats. He subsequently chose himself to fill one seat after his resignation, though the other seats are still not filled. He also reportedly had lobbied remaining executives and some board members to persuade the board to return him to an operating role.

Benchmark said in the suit that it would not have allowed those new seats if it had known about the “gross mismanagement and other misconduct at Uber.” Kalanick hasn’t helped himself either, getting caught on camera berating an Uber driver and, in another incident, sending a memo to his staff on “sexual rules of engagement” that detailed under what situations they could and couldn’t have sex during an employee event in Miami.

The VC firm also charged that Kalanick promised in his resignation agreement that the two board seats would be independent, which is why Benchmark didn’t act earlier. Benchmark is asking for the June 2016 stockholder agreement to be invalidated, eliminating all three board seats — which would remove Kalanick from the board as well.

Kalanick was quick to respond through a spokesperson, according to Recode:

“The lawsuit is completely without merit and riddled with lies and false allegations. This is continued evidence of Benchmark acting in its own best interests contrary to the interests of Uber, its employees and its other shareholders. Benchmark’s lawsuit is a transparent attempt to deprive Travis Kalanick of his rights as a founder and shareholder and to silence his voice regarding the management of the company he helped create. Travis will continue to act in the interests of Uber and all of its stakeholders and is confident that these entirely baseless claims will be rejected.”
