Yes, absolutely there's a potential. It all comes down to the warning given to the jurors and letting the jurors know the potential consequences. We're running into that in the United States, and here as well, with jurors looking up things on their smart phones online, even when they're not being sequestered.
Some jurors are going to violate that law and do so anyway. I assume that if they're sequestered and their devices are taken away, they may not have the ability to do that, but I don't think that the benefit of sequestration outweighs the risk in terms of the added burden that it puts not only on jurors but on the system as well.
