Definition - What does Competence mean?
Competence refers to qualification or credibility to do a certain thing. In the context of the law, witnesses, courts, testators and other parties are all judged to make sure they have necessary competence to perform their duties. If they are not deemed to possess full competence to perform their duties, then they can be stripped of their powers.
Justipedia explains Competence
Witnesses can be classified as incompetent by the court if they do not possess the requisite intelligence to evaluate the circumstances due to a disability, if they have a direct conflict of interest in a case, or if the court believes that they cannot give a credible testimony for another reason.
The legal system aims to make the legal process as fair and accurate as possible. Therefore, competence is taken seriously. Courts become competent or qualified to try certain cases once a government body has given them that authority.
