Beginning July 27, Washington will become the first state to require transaction parties in any industry to file an application if certain criteria are met. The new laws reflect a growing trend of states asserting jurisdiction over antitrust in ways that can conflict with federal requirements, complicating timelines, business plans and closings for buyout shops, two attorneys at Goodwin told The Deal. “There are certainly timing implications. Some of these states can take up to 180 days for a review period,” said John Goheen, an Antitrust partner at Goodwin, referring to Oregon and California, which can extend those windows to 270 days or longer. “The mini-HSRs really started to come into vogue five years ago based on a concern about the impact on healthcare costs and healthcare access that could result from market consolidation,” said Joseph Harrington, a partner in Goodwin’s Private Equity group who specializes in healthcare law.
