Right-wing justices adhere faithfully to an immutable document:
The Republican Party Platform.
Erwin Chemerinsky explains in the Sacramento Bee. A snippet (emphasis added):
It was striking that the conservative justices professed the need to defer to Congress when that supported a conservative result and to give no deference when it wouldn’t. And in cases involving federal statutes, time and again, the conservative justices went out of their way to protect big business over the interests of employees, consumers and small business even when it meant negating the clear will of Congress.
For decades, conservatives have professed a belief in judicial restraint and a desire to decide cases based on a neutral judicial methodology. This term, as much as any, shows that this is nonsense and it is an emperor with no clothes.
