An evenly divided New Jersey Supreme Court has let stand a lower court’s ruling rejecting prosecutors’ attempt to carve out a good-faith exception to the exclusionary rule, which says arrests or searches and seizures must be declared invalid if the police acted without obtaining a warrant or did not have probable cause.

The 3-3 split in State v. Shannon on Aug. 19 means an Appellate Division ruling that evidence seized after an arrest based on an invalid arrest warrant must be suppressed is affirmed.
