Don't give a crap. This is an example where there has been an oversight. Apparently the people who think up this sort of lawyer crap didn't think of everything.
We have a situation where the "evidence" doesn't actually prove the thing needing to be proven. Ergo, the methodology for accepting unproven claims as "proven", are faulty.
It was Congress that came up with the federal rules of evidence in 1975 but any judge can interpret them as he or she sees fit.
They are guidelines, not laws. Most judges tend to follow them pretty closely though.
Congress and state election officials don’t use them at all.
In the interest of resolving the birth certificate component of the Obama/natural born citizen issue once and for all, I wish that someone had been able to convince a judge or congressional committee chair that there was a legitimate reason to issue a court order or a congressional subpoena for the vault edition Certificate of Live Birth. But that never happened.
