Except it isn't European data, Its an American's data stored under a European account in European servers. Small difference.
It is not the data that is the issue.
It is a US Judge requiring a company to reach out across international borders and
as an agent of the judge grab the data and spirit it across international borders and
deliver it to the judge. This something that the US judge could not require of the
State Department, CIA or NSA any other government agency to do.
If it was not data the rule would be more obvious. If a storage company had
a large box of cigars perhaps from some random country close to Florida could that
company be compelled to ship that box of cigars to the judge to determine
if the owner of the box of cigars was engaging in the trade of and trade with
a foreign country that the US has issues with. Only by inspection of the
contents of the box would the judge know.
Now it is possible that Cuban cigars are no longer the smoking gun of illegal
trade with Cuba but the point is that this judge is forcing a company to reach out
across international borders and do the judges bidding.
What if the company name was Blackwater Security Consulting (since renamed Academi)
and that company was directed by a judge to import or export anything or anyone
at the behest of the judge (with or without payment for services BTW).
If it was a physical container the decision in my mind is obvious
that the judge is reaching, reaching, reaching well beyond charter and
jurisdiction.
It gets more interesting if the transport of the physical container crosses
other international borders. Most nations have laws that prohibit trafficking
in stolen goods. So a packet map showing how each and every fragment
of this container traveled could also be a topic of a United Nations inquiry.
Blood diamonds, ebony, ivory... trafficking in crime tainted desirables and
this judge covets this stuff.
