> a judge still needs to issue a warrant for the police to actually go and look at the file Only in the future. Maher's conviction, based on the warrantless search, still stands because the court found that the "good faith exception" applies--the court affirmed the District Court's finding that the police officers who conducted the warrantless search had a good faith belief that no warrant was required for the search…
I wonder what happened to fruit of the poisoned tree? Seems a lot more liberty oriented than "good faith exception" when police don't think they need a warrant (because police never seem to "think" they need a warrant).
The court ruled that at the time, when the State Police opened the file, they had no reason to believe that a warrant was required. While the search was later ruled unconstitutional, no court had ruled it was unconstitutional *at the time of the search*. One of the cornerstones of American jurisprudence is that you cannot go back in time and overrule decisions based on contemporary jurisprudence.
From the opinion: 'the exception can also apply where officers “committed a constitutional violation” by acting without a warrant under circumstances that “they did not reasonably know, at the time, [were] unconstitutional.”'
If you're interested, the discussion of a good faith exemption (and why fruit of the poison tree doesn't apply here) begins at page 40 of the doc.
