IANAL and you should probably contact yours about such things but a straightforward reading suggests that because you knew you were downloading something likely illegally gotten, you are in fact on the hook for downloading it.

    “Misappropriation” means: 

      (i) acquisition of a trade secret of another by a person who knows or has
        reason to know that the trade secret was acquired by improper means; or
      (ii) disclosure or use of a trade secret of another without express or
        implied consent by a person who 
        (A) used improper means to acquire knowledge of the trade secret; or 
        (B) at the time of disclosure or use knew or had reason to know that
          his knowledge of the trade secret was 
          (I) derived from or through a person who has utilized improper means 
            to acquire it; 
          (II) acquired under circumstances giving rise to a duty to maintain
            its secrecy or limit its use; or 
          (III) derived from or through a person who owed a duty to the person
            seeking relief to maintain its secrecy or limit its use; or 
        (C) before a material change of his position, knew or had reason to
          know that it was a trade secret and that knowledge of it had been
          acquired by accident or mistake.

Ahem. Not seeding is a crime.

Depends heavily on the jurisdiction, I am afraid. This exact case was used as a precedent where I'm from (Czech Republic) that no, merely downloading over BitTorrent still constitutes "sharing copyrighted material".

Presumably that was because BitTorrent sends data even before receiving 100% of it? But I assume that downloading these files would not be allowed in this case anyway as per Zákon č. 121/2000 Sb. §29 (2) since this is not a published work.

The only place I know where that would be the case is Switzerland, there downloading copyrighted material isn't illegal (and companies aren't allowed to track IPs of people downloading files via torrent), but sharing is. But in the context of a data leak of confidential trade secrets, that's likely to be a completely different situation.
