It won't stand because it's not pragmatic. The issue around 'passwords being in your mind' is interesting, but they'll move past it. If you have evidence of a crime on your phone, it must be part of the process. There's nothing remotely unlawful about search of property so long as there is merit, oversight, warrant etc.. Ultimately, this will be no different than searching your car. Now, the cops doing it without a w…
The issue arises when the knowledge of the password itself is incriminating. The 5th amendment prohibits forced self incrimination. Forcing a suspect to divulge information that is directly incriminating will not stand constitutional review, regardless of the nature of the information. You have the right to remain silent.
Even if your encrypted laptop contains evidence, you cannot plead the fifth if the prosecutors know it’s there. As long as they can get a warrant and when they get the data say “see your honor? Here is the evidence we knew was there!”, it doesn’t fall under the fifth.
Self incrimination would be if you are charged with tax fraud and proof is on your encrypted drive and the prosecution knows this, but also on that drive is records of money laundering, a separate crime they do not know about. This is when pleading the fifth would apply. By decrypting the laptop, you would incriminate yourself in a second crime, that you were not being charged with. Presumably if you were coerced into decrypting the laptop in this case, you could use the argument that the money laundering evidence can not be admitted into court because it was obtained inappropriately.
IANAL and this ain’t legal advice. Stay in school kids.
