Re: On Digital Evidence and "The Cloud"
And that scenario only works if the legal dispute in question is, "The State vs. Company X".
It has no effect - no possibility of bearing - if the plaintiff is a different company and this is e.g. a contractual dispute, or a civil matter rather than a criminal complaint. Yet the rules of evidence - albeit with the potential to be expressed slightly differently - are potentially powerless here. [ The potential to be expressed slightly differently comes from responses related to e.g. a witness taking the 5th Amendment. In a criminal matter, a jury would be instructed that they cannot take a negative inference from that response. In a civil matter, it can absolutely be inferred to the detriment of the respondent.]
However, if it is a contractual or civil law matter, it would be *exceedingly* difficult to go to Court and ask for the civil equivalent of a "search warrant" - i.e. some kind of legally enforceable preservation order - because of the distinction between the two legal frameworks. In a civil dispute, the plaintiff can basically ask for all they want, but they can't turn to the Court and ask the *Law* to help enforce it. As you quite rightly point out, in a *criminal* case, the Court can absolutely do that - the State can apply to the Court for a warrant that would allow them to "search and seize" evidence indicative of the alleged crime.
Let's look at this from a slightly different direction... A publicly limited company has to have it's financial declarations - it's annual report, it's 10-Q, in fact all it's internal financial data - independently audited to ensure that the truth aligns with the published claims. This became a legal requirement when companies abused the "trust" of investors and lied about their financial performance: enough people were harmed that laws were enacted to make such practices criminal.
Over the last 20-30 years, so much of our lives have become digital that we take it for granted... The thought of going to a library, or begging parents to invest in a copy of Encyclopedia Britannica - just so you can find information on something... well, that's basically a joke to us today. Yet even though we seem to have adopted "digital contracts" in some areas of business [usually where the party likely to be disadvantaged is Joe Public], yet there are very few pieces of legislation that require similar controls on corporate practices. It's a bit of a stretch, but one example I can think of is French VAT law, through which businesses must "guarantee the integrity, legibility and authenticity" of an invoice - so when the invoice is submitted electronically, the issuer has to use technological means (such as digital signatures, though that is not the only accepted solution) to evidence the integrity of said invoice.
But the bottom line seems to be:
"If a court is likely to place any standing on any piece of digital evidence in a legal dispute, then it should follow that appropriate laws must be enacted to require any evidence that may later be relied upon in Court to be verifiably protected such that it's authenticity, integrity and legibility are retained".
Or to go back to our general example... Say you and I represent different companies in a legal dispute. You represent the plaintiff and in the dispute, you go to a Court and say, "Your honor, on information and belief, we allege that the scurrilous defendant over there has emails that contain proof of their contractual breaches. We would like to ask for limited discovery, of their email archives, to surface that evidence..."
If the Court agreed that your claim was valid, I would then be asked to not simply produce all relevant emails... but, critically, provide evidence that shows that the search was complete, thorough, covered all agreed search terms of the entire email history for all identified employees, contractors and agents and, critically, can prove that authenticity with appropriate digital signatures accompanying the evidence.
And that takes us to the "fun bit", which is that if I *can't* produce that evidence, then the relevant civil law would allow the plaintiff - that's you - and the Court to take the most negative possible inference. In other words, it would allow the Court to conclude that because I couldn't prove my email responses were "complete", the Court would be entitled to conclude nefarious malpractice on my part.
*That* would put all corporations on notice that they had better be "on their game" with respect to evidence preservation. It would also require companies to get much tighter about e.g. the use of ephemeral messaging solutions [WhatsApp and Signal] on the part of their employees.
Does all this sound a bit over-the-top or far-fetched? Well guess what - regulations have already been introduced to require this of the financial industry. After the LIBOR scandal that took place between 2005-2009, banks were required by regulators to enact all sorts of safeguards to prevent "regulated employees" / "regulated individuals" from using unauthorised technology to communicate.
So it can be done. And it *has* been done, when it has been shown that without regulation malpractice led to widespread harm.
I have to say that in the case of publicly elected or appointed officials, such activities should not just be "immediately impeachable", but such that they render the participant *immediately* liable for criminal charges. Without adequate enforcement - with teeth - the malpractice will continue.
