Seattle's City Council approved an ordinance on June 2 that will gradually raise the city's minimum wage to $15 an hour; Mayor Ed Murray signed the ordinance into law the next day. The law gives large businesses, defined as any company with more than 500 employees, over three years to implement the changes. Smaller businesses are given an extra four years to phase in the increase. Because franchises are part of national company networks employing, typically, over 500 people, local franchises of larger corporations must adhere to the three-year schedule.
The IFA lawsuit seeks an injunction to prevent the law from going into effect, claiming it violates both the Equal Protection Clause and Commerce Clause of the US Constitution.
