A Supreme Court decision should only be for one reason; to compare other laws to determine if they comply with the Constitution. That is the Supreme Court’s sole function.
A majority opinion of attorneys, citizens, or judges does not trump the Constitution. The Constitution provides an amendment process when the nation chooses to install change. The Constitution provides no other vehicle for change.
It's a funtion not listed in the Constitution, except perhaps by implication. There are several other classes of cases listed where the Supreme Court has original or appellate jurisdiction.
Section. 2. The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority; — to all Cases affecting Ambassadors, other public Ministers and Consuls; — to all Cases of admiralty and maritime Jurisdiction; — to Controversies to which the United States shall be a Party; — to Controversies between two or more States; — between a State and Citizens of another State [Modified by Amendment XI]; — between Citizens of different States; — between Citizens of the same State claiming Lands under Grants of different States, and between a State, or the Citizens thereof, and foreign States, Citizens or Subjects.
In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.
