no one should be (the|) judge in his own cause
1
used to suggest that a person cannot make an unbiased decision about a matter in which they are directly involved
The origin of the proverb "no one should be judge in his own cause" is rooted in legal and philosophical traditions, dating back to ancient Roman law. The saying emphasizes the need for an unbiased third party to make decisions in disputes, as those involved may not be able to evaluate the matter objectively. It highlights the importance of fairness and neutrality in decision-making, especially when personal stakes are involved.
- Even if one is confident in his innocence, it is not appropriate to be a judge in his own cause, as it undermines the credibility of the decision-making process.
