The two correct answers that guide Supreme Court justices when forming a legal opinion are:
- Constitutional principles
- Stare decisis
Constitutional principles refer to the foundational rules and rights established in the U.S. Constitution, while stare decisis means the legal doctrine of adhering to precedent in making judicial decisions. Evidence and majority opinion are not guiding principles in the same way. Judicial review is the process by which the Supreme Court evaluates the constitutionality of legislative and executive acts, but it is not a guiding principle in forming an opinion itself.
