Bad guys overrule good guys at Supreme Tribunal

The presidential recall vote in Venezuela is off again, after the pro-Chavez Constitutional Chamber of the Supreme Tribunal overruled the anti-Chavez Electoral Chamber of the Supreme Tribunal yesterday. Creative jurisprudence, they call it.

One thing I just don't understand and maybe someone can explain to me in the Comments' section: as I understood it, the revision process was meant as a safeguard for very basic constitutional principles. What, according to the Constitutional Chamber, is the foundational constitutional principle violated by the Electoral Chamber's decision? I just don't understand their reasoning...

Duque's dad: pissed.
