DEUT967 Biblical law exacts what is, as far as I know, a unique and uniquely fair punishment for false witnesses: "And you shall do to them what they schemed to do [to their victim]" [this verse] Thus, lying witnesses who make a false claim of $10,000 should themselves be fined $10,000, well Jewish law rules that witnesses who tried to have capital punishment inflicted on an innocent person pay that penalty themselves.
