Until it's replaced with something better, the justices should interpret the law so that that it does the right thing if it's a moral issue and the smart thing if it's not. I can't give that a label.
That is essentially the "living document" approach,
ie, the law means what we want it to mean.
Example....
The 6th Amendment states.....
"In all criminal prosecutions, the accused shall enjoy the right to
a speedy and public trial, by an impartial jury....."
Under the living document philosophy, the court has ruled that
we're not really entitled to a jury trial if it inconveniences government.
So they apply the "Petty Offense Doctrine" to say that if one faces
less than a year in jail, then government may unilaterally deny the
right to trial by jury.
Thus, the courts can take away constitutionally granted rights
by fiat. Amending the Constitution isn't all that necessary.
