MIRANDA INVOCATIONS ONLY LAST FOR 14 DAYS

The Court has held that a Miranda invocation will only remain in effect for 14 days. In Maryland v. Shatzer, the Court held that an inmate's invocation of Miranda did not carry over to a subsequent interrogation that occurred two years later.

This ruling, which came without dissent, is understandable given that a span of two years occurred between interrogations.
