A federal judge in San Francisco this week let the majority of the claims survive in a proposed securities class action against the organizers of the Tezos initial coin offering.

Although U.S. District Judge Richard Seeborg’s 19-page ruling issued Tuesday was far from the final word on whether the Tezos ICO ran afoul of U.S. securities laws, he let one defendant—Bitcoin Suisse AG, which provided intermediary services from some foreign investors in the ICO—out of the lawsuit altogether.
