Slippery-Slope Principle Law & Legal Definition


Slippery slope principle refers to an argument that every relaxation of a constitutionally imposed restraint is an invitation to justify some other or further relaxation of that restraint. This principle is usually raised in the context of legalized human euthanasia and in other contexts, such as the right to protection from unreasonable search and seizure.

Slippery slope principle is also known as Wedge principle or parade-of-horrors objection.
