Tesla, the electric car company based in California, is suing Michigan over its law that prohibits direct-to-consumer sales of cars.
In 2014, the Michigan state legislature essentially Tesla-proofed an existing law at the urging of auto dealers.
The law makes it clear that car companies can sell their products only through licensed dealers. Tesla sells its cars directly to consumers out of stores it owns.
Tesla says the Michigan law violates its constitutional right to due process and equal protection, as well as restricting interstate commerce.
