Understanding Nemo Allegans Suam Tupitudinem Audiendus Est in Law

Definition & Meaning

The phrase "no one alleging his/her own turpitude is to be heard as a witness" suggests that a person cannot testify in a legal matter if they are claiming their own wrongdoing. This principle is rooted in the idea that a witness's credibility can be compromised if they are admitting to immoral or unethical behavior. While this phrase is not commonly applied as a strict rule of evidence, it can influence cases where a party is trying to assert a right based on illegal actions.
