Question

What idea was the decision in Griswold v. Connecticut based upon?

If the Constitution forbids self-incrimination, husbands and wives should not be forced to testify against each other.
The Constitution cannot possibly include all rights, so judges can create new ones based on what the founders must have been thinking.
If the Constitution forbids unreasonable searches, there must be a reasonable right to privacy.
The Constitution does not meet everyone’s needs, so citizens can disregard laws when they think the government is violating their rights.

Answer 1

"If the Constitution forbids unreasonable searches, there must be a reasonable right to privacy."

Griswold v. Connecticut (1965) held that the Constitution protects a right to marital privacy (derived from the "penumbras" and guarantees of the Bill of Rights and the Fourteenth Amendment), and struck down a law banning contraceptives for married couples.
