Nemo judex in causa sua

Nemo judex in causa sua

Literal Meaning

 “No-one should be a judge in his own case”.

Origin

The phrase is credited to Sir Edward Coke in the 17th century.[3]

It is also found in The Moral Sayings of Publius Syrus, a Roman Slave (1856), by Darius Lyman, Jun., A. M.

Explanation

Nemo judex in causa sua (or nemo judex in sua causa) is a Latin phrase that means, literally, “no-one should be a judge in his own case.” It is a principle of natural justice that no person can judge a case in which they have an interest.[1] The rule is very strictly applied to any appearance of a possible bias, even if there is actually none: “Justice must not only be done, but must be seen to be done”.

This principle may also be called:

  • nemo judex idoneus in propria causa est
  • nemo judex in parte sua
  • nemo judex in re sua
  • nemo debet esse judex in propria causa
  • in propria causa nemo judex

The legal effect of a breach of natural justice is normally to stop the proceedings and render any judgment invalid; it should be quashed or appealed, but may be remitted for a valid re-hearing.

Illustration

If one sits in his own case as a judge and decides the case, the justice delivery system will never be free from criticism. So it is imperative that no one shall be a judge in a case where s/he is either directly or indirectly a party
