No. You are arguing a lost case. Again, the problem is not that the data is outside the country. The problem is that the judge has ordered them to produce the information. This is not some silly request by the judge asking them with a "pretty please". They are to present the information to the court (aka judge and jury) as a result of a ruling by the judge. This is what is meant by "obligated by law".
Now you can tell the court No, but it will be held against you. Yet, this is what they are trying to do. They had their chance to deny the information before the judge order them to provide it. They did not successfully fight it and lost at this particular stage. Now they are trying to twist it and to throw the court off, or, perhaps these e-mails contain information that is going to put them into much deeper trouble than they are already in. There is certainly a reason why they are not following the law here.
Think of it as a murder suspect who is being charged with murder and who claims to have an alibi, perhaps a witness who is now living outside the US... The court now orders the suspect to bring the witness into the trail or else will the alleged alibi be of no use.
Another example is a missing murder weapon... The attorney may have the dead body and they have witnesses, but they are missing the murder weapon and are now demanding of the suspect to provide information about the weapon's location. Could be the suspect is innocent, knows about the location of the weapon, but does not want people to know where to find it. Maybe the weapon is a 25kg gold bar, or the weapon was used in another murder case, etc..
To give a third example, think of a criminal who committed a crime in the US and now flees the country. It may save the criminal from being sentenced to prison by a US court, but it is not going to prove the criminal's innocence and make the charges go away.
In this case, with the e-mails, does it very much depend on what these are needed for. Their content, if provided, may or may not change the course of the trial. It all depends. Not following a judge's ruling is however always a bad idea. Maybe they have something to hide, maybe they do not and the companies' lawyers only want to stretch the trial to make more money, etc.. For the judge and jury will it make no difference if these e-mails are within the US or outside the US. Only their content will be of importance, not their location.
Whatever, when you are obligated by law to produce the information then it means you have to, or a refusal to do so will be used against you. For all it matters could the missing information have been lost. It will not make the judge or the jury happy, and you do want them to vote and rule in your favour, right?
