        Illegal Predicate Searches and Tainted

             Warrants After Heien and Strieff


                                Kit   Kinports*


      A  long-standing debate has surrounded the relationship between two features of the
Fourth Amendment's  exclusionary rule-the fruits of the poisonous tree doctrine and the
good-faith exception-in cases where the evidence used to secure a search warrant was
obtained in violation of the defendant's constitutional rights. Some judges and scholars
maintain that the fruits of the poisonous tree doctrine takes precedence in such tainted
warrant cases, leading to the suppression of any evidence seized in executing the warrant
unless the warrant was supported by probable cause independent of the illegal predicate
search. By contrast, others believe that the good-faith exception should be available in these
circumstances because the police acted in reasonable reliance on a search warrant.
       Evo recent Fourth Amendment  opinions issued by the Supreme Court-the   2014
mistake of law ruling in Heien v. North Carolina and the 2016 fruits of the poisonous tree
decision in Utah v. Strieff-limited the consequences of errors police make in conducting
Terry stops and potentially have implications for the tainted warrant cases. In examining the
impact these two opinions may have on the admissibility of evidence seized pursuant to a
tainted warrant, this Article approaches the tension between the poisonous tree doctrine and
the good-faith exception first by disaggregating the tainted warrant cases depending on what
type of law enforcement mistake led to the unconstitutional predicate search and then by
analogizing to the standards of appellate review.
      A warrant may be tainted because the officer conducting the predicate search made a
mistake offact, a mistake about the reach ofstate criminal law, a mistake about the existence of
probable cause or reasonable suspicion, or a mistake about some other substantive Fourth
Amendment   doctrine. Examining each type of error in turn, the Article concludes that the
Court's current Fourth Amendment jurisprudence is adequate to address all varieties of
tainted warrants, that law enforcement misinterpretations of state criminal codes can be
evaluated under Heien, and that Strieff 's attenuation analysis does not call for excusing any
additional tainted warrants. The Article therefore argues against extending the good-faith
exception to save any tainted warrant that cannot survive under the Court's existing case law
and that is not supported by probable cause independent of the impermissible predicate search.
