That's not something unique about "this new court". The Court has never been all that respectful of precedent. From the Lochner era (reading a right to expansive freedom of contract into the constitution), to the "switch in time that saved nine" (vastly expanding the definition of 'interstate commerce' such that Congress could regulate anything), to the Warren court (which invented whole-cloth a slew of social and criminal justice rights), the Court has often gone in radical new directions and overruled previous decisions.
