Expert witnessAn expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as an expert. The judge may consider the witness's specialized (scientific, technical or other) opinion about evidence or about facts before the court within the expert's area of expertise, to be referred to as an "expert opinion".
Judgment (law)In law, a judgment, also spelled judgement, is a decision of a court regarding the rights and liabilities of parties in a legal action or proceeding. Judgments also generally provide the court's explanation of why it has chosen to make a particular court order. The phrase "reasons for judgment" is often used interchangeably with "judgment," although the former refers to the court's justification of its judgment while the latter refers to the final court order regarding the rights and liabilities of the parties.
