If a legal decision is made upon personal judgment rather than established law, it can be termed as:

• A. Assent
• B. Arbitrary
• C. Appropriation
• D. Arguendo

Answer: (B)

When a legal decision is made based on personal judgment rather than established law, it is described as arbitrary. This term signifies that the decision lacks a grounding in legal precedent or established rules, making it subjective and potentially capricious. Arbitrary decisions can lead to inconsistencies in the legal system, as they do not adhere to a rational basis or known standards of law.

The focus on personal judgment implies that the ruling derives from an individual's discretion rather than a structured legal framework, which is critical in maintaining order and fairness in judicial proceedings. In contrast, the other terms provided have different meanings and do not convey the same idea of a decision that is made without legal justification. For example, assent refers to agreement, appropriation pertains to the act of taking something for one's own use, and arguendo means "for the sake of argument," which does not relate to the nature of decision-making in legal contexts.
