Commodum Ex Injuria Sua Nemo Habere Debet

Latin: a wrongdoer should not be enabled by law to take any advantage from his actions.

Also presented as commodum ex injuria sua non habere debet.

From Roman law now a significant part of the common law's tort law and civil law (civil liability).

Not all translations are identical but the core remains the same. Some other examples:

• No person ought to take advantage from his own wrong;
• Nobody ought to derive advantage from his injurious behaviour; and
• No one ought to profit from his own tort.

Ancillary and similar to crimen omnia ex se nata vitiat.

Commodum ex injuria sua non habere debet is the rationale behind statutes that prevents criminals from retaining the known profits of their crimes or even from collecting on royalties tendered for book or movie deals in regards to their actions.
