Well, the fact that the Philadelphia soda tax has been upheld by the Pennsylvania courts wasn’t enough to discourage the Illinois Retail Merchants Association from filing a court challenge to the new Cook County soda tax. The group filed a lawsuit asking for a temporary restraining order and a preliminary injunction in Cook County Circuit Cook on the grounds that the new sugary beverage tax is unconstitutional and too vague to implement. An emergency hearing on the suit was scheduled for yesterday afternoon following the initial hearing Wednesday, at which Judge James McGing recused himself from the case. Cook County authorized the tax, which is set to become effective tomorrow, some number of months ago. Since that time, a growing number of towns within the county have formally voted to opt out of the mandate.
