Bill -- thanks. I was wondering about this.Looks like the Pennsylvania constitutional provision in play here was approved by the legislature.
The "legislature" acts in a number of different ways. It passes election laws (which have to be signed by the gov fyi), it passes emergency laws, it passes laws setting up election boards to which certain regulatory powers are delegatd to, it passes a state constitution, etc. Basically the "legislature" is the whole legal system, typically review-able by the courts of such state.
Seems quite anti-conservative and anti-states rights to say that SCOTUS gets to be the general court of appeal loomimg over state supreme courts due to the wording of Art 1, section 4.
Some people might see that more as unaccounted unelected federal authorities over stepping their bounds in search of an outcome?
