IF the judge in California demands the results not be destroyed and supponeas the doctor to appear in California before him with the results then they will not be destroyed, but if the Bahamian court orders them destroyed and no court in the USA steps in to stop it they will be destroyed. Sad, but true....
The Bahamians do not have jurisdiction since the results are on US soil. The results belong to Larry not the Bahamian courts. It will be up to Larry when he wants to play the "out of jurisdiction" card.
No US court would uphold a Bahamian order because Stern signed off on the the DNA test and because they are now in US custody.
Now if the everything had stayed in the Bahamas that would be a different story.
