Mishnah — Seder Nezikin, Tractate SanhedrinChapter 4…
“ Cases of money, all can rule for acquittal or conviction; cases of life, all can rule for acquittal but all cannot rule for conviction. Cases of money, one who convicts can acquit and one who acquits can convict; in cases of life, one who convicts can acquit, but one who acquits cannot turn and convict. Cases of money can be tried in the day and can finish in the night; cases of life are tried in the day and must finish in the day. ”
