Answer:
a. The Supreme Court could reserve a law.
Step-by-step explanation:
If a court decides that something — a law, an appointment, and an action — is unconstitutional, they are — on the face of it — saying it is a legal nothing. Sometimes that is reasonably straightforward. Eight sections of the Security Laws (Amendment) Act, 2014, were declared unconstitutional early in 2015. If it keeps going to the Supreme Court and they declare it unconstitutional, then the courts under them must fall in line. Depends on you where that unconstitutional or unjust law stops. If it’s a Federal law, the states are unaffected.
