Hugo Black,
Hoopeston Canning Company v. Cullen…
“ Of necessity, any regulations affecting the solvency of those doing an insurance business in a state must have some effect on business practices of the same company outside the state. Nothing in the Constitution requires a state to nullify its own protective standards because an enterprise regulated has its headquarters elsewhere. The power New York may exercise to regulate domestic insurance associations may be applied to foreign associations which New York permits to conduct the same kind of business. ”
