Does a State's workers compensation statute violate Equal Protection when it treats Minnesota residents injured on the job in Minnesota differently based on whether the employer is located in North Dakota rather than any other State?

QUESTIONS PRESENTED Does a State’s workers compensation statute violate Equal Protection when it treats Minnesota residents injured on the job in Minnesota differently based on whether the employer is located in North Dakota rather than any other State? Where a Minnesota resident, whose payroll taxes are paid to Minnesota, is injured on the job in Minnesota, can the State of Minnesota deprive him of a common law cause of action, as well as deny him workers compensation benefits, by mandating that his exclusive remedy is in the workers compensation system of North Dakota because that is the home of the worker’s employer?
