His High Judgmental Supremacy, Judiciary Pag, L.I.V.R. (the Learned, Impartial, and Very Relaxed) was the Chairman of the Board of Judges at the Krikkit War Crimes Trial. He privately called himself Zipo Bibrok 5 × 10 to the 8 (spelt Big Ten, little eight) (which is five hundred million, or half a billion in short scale).

It was Judiciary Pag's idea that the people of Krikkit be permanently sealed in a Slo-Time envelope, and the seal could only be broken by bringing a special Key to the Lock. When the rest of the universe had ended, the seal would be broken and Krikkit could continue a solitary existence in the universe. This judgement seemed to please everybody except the people of Krikkit themselves, but the only alternative was to face annihilation.

Pag's real name shares some similarities with that of Zaphod Beeblebrox, suggesting that he may be a distant ancestor (actually, due to an "an accident with a contraceptive and a time machine", Zaphod's ancestors are actually his descendants). Pag's casual and relaxed demeanor also suggest a family relationship to Zaphod.
