This is not true. The Challenge is designed as best as can be, but there is no rule saying Randi can't decide on his own if a test is or isn't passed apart from the conclusions of the test givers.
...
Ruach1, you may spin it how you see fit.
However: The JREF Challenge does not involve Mr. Randi "deciding if a test is or isn't passed" upon his own or somebody else's "conclusions".
The decision rests upon the pre-negotiated Challenge Protocol.
Almost like a lottery ticket.
No judging involved.
No decisions necessary.
You either do not win or you do win. Badabing-badabum. (Hey, if you apply properly, you can make Mr. Randi "an offer he can't refuse.")
