Declaring administrative hearings a violation of the 7th amendment is an enormous ruling. it's been considered constitutional because you can always appeal the agency ruling in district court, which is incredibly expensive and as a result almost noone ever does it, but you theoretically can.

If SCOTUS backs this it will basically dismantle the administrative state.
