In a controversial ruling last month, Koh struck down Google’s defenses to claims that it violated the federal Electronic Communications Privacy Act and state privacy laws by scanning Gmail messages to help sell ads. At a hearing on Tuesday, Google lawyer Kathleen Sullivan of Quinn Emanuel Urquhart & Sullivan pressed Koh to certify her order for interlocutory review, arguing that the judge had tackled novel legal questions which could reshape technology companies’ interactions with users.

“It is important not just for getting this case right but for getting other cases right that are going to determine the course of business in the Valley,” said Sullivan. She pointed to a similar suit filed against Yahoo Inc. the week after Koh’s order.
