Plato, Laws 937d

ἥμισυ μαρτυριῶν καταδικασθῶσίν τινες, τὴν κατὰ ταύτας ἁλοῦσαν δίκην ἀνάδικον γίγνεσθαι, ἀμφισβήτησιν δʼ εἶναι καὶ διαδικασίαν εἴτε κατὰ ταύτας εἴτε μὴ ἡ δίκη ἐκρίθη, ὁποτέρως δʼ ἂν κριθῇ, ταύτῃ γιγνέσθω τὸ τέλος τῶν ἔμπροσθεν δικῶν.πολλῶν δὲ ὄντων καὶ καλῶν ἐν τῷ τῶν ἀνθρώπων βίῳ, τοῖς πλείστοις αὐτῶν οἷον κῆρες ἐπιπεφύκασιν, αἳ καταμιαίνουσίν τε καὶ καταρρυπαίνουσιν αὐτά· καὶ δὴ καὶ δίκη

the action that was lost because of them shall be annulled, and there shall be a disputation and a trial as to whether the action was or was not decided on the evidence in question; and by the verdict then given, whichever way it goes, the result of the previous actions shall be finally determined. Although there are many fair things in human life, yet to most of them there clings a kind of canker which poisons and corrupts them.
