Our runners up for Litigator of the Week include King & Spalding's Jim Boswell, Peter Strotz, Mike Paulhus and Stephanie Johnson, who secured a complete defense verdict on behalf of Prime Healthcare, a 45-hospital system, against the California Department of Insurance. 

The state alleged Prime made at least 1,858 fraudulent insurance claims, and sought damages of at least $57 million, subject to trebling. But after a bench trial, Los Angeles County Superior Court Judge William Fahey found no evidence of fraud, ruling that the California Department of Insurance "vastly overreached in pursuing a case beyond its limited jurisdiction." 

Robbie Kaplan and John Quinn of Kaplan Hecker & Fink scored a groundbreaking ruling in the SDNY when U.S. District Judge Lorna Schofield authorized immediate discovery against President Donald Trump, his older children and their company in a putative class action.

The Kaplan team represents plaintiffs who say they were defrauded by the Trumps into investing in a business opportunity offered by non-party American Communications Network, and that the Trumps hid the fact that they were paid for their endorsement.

A follow-up court order protects the plaintiffs' pseudonymous status through discovery and prohibits President Trump or the other defendants from contacting them directly (or more importantly, savaging them on Twitter).

Gibson, Dunn & Crutcher's Mark Kirsch won dismissal of a shareholder class action against AmTrust Financial—which is impressive, but the real feat was that he did so despite an open SEC investigation and the company's restatement of financials.

Goodwin Procter partners Neel Chatterjee and Michael Jones notched a win on behalf of Indian Institute of Technology in a long-running fight over technology that permits applications to function on handheld devices without an internet connection. 

Plaintiff M.A. Mobile claimed that the institute breached a non-disclosure agreement signed in 2003 for a joint venture and commercialization of the technology. But a federal judge in San Francisco granted summary judgment in favor of Indian Institute of Technology, ruling that M.A. Mobile's claims "rely on speculation rather than evidence and inference."

O'Melveny & Myers partners Jonathan Rosenberg and William Pao convinced a federal judge in Manhattan to dismiss securities class action against Chinese technology firm Xunlei Ltd. without leave to amend. The case involved novel issues at the intersection of blockchain and the legality of initial coin offerings under Chinese law.

Finally,Paul Curnin and Craig Waldman at Simpson Thacher & Bartlett won two motions to dismiss shareholder class actions against client Valeant, both before U.S. District Judge Michael Shipp in New Jersey.
