Yes... when the time comes - it is all in Larry's hands when he wants to decide to play the "out of jurisdiction card" - The California Courts have already agreed to accept the Ohio DNA Lab results as Official and in Good Standing in California when the time comes for that.
Like I said the Ohio DNA lab probably is not worried if they are ever asked again to come to the Bahamas to do a DNA swabbing or to run DNA tests for the Bahamas. DNA guy probably has no interest in ever vacationing or visiting the Bahamas again.
There is no court in the USA that would uphold the Bahamian sealed court order if they tried to push the issue in a US court. The DNA swabbing was done in a controlled environment (Doctors office) and while Stern was standing right there. Stern also agreed to using Larry's DNA guy and DNA lab.
If I was Larry I'd have played the California card today after the trick Stern pulled yesterday and after today it would be a no-brainer. We read how the Bahamian Supremes are underpaid -- aka probably easy targets for Team Stern to slip money under the table to get things to go his way.
