A more thorough explanation: Ambiguity upon the factum refers to a situation where there is uncertainty or lack of clarity regarding the facts or circumstances of a legal case or issue. This ambiguity can arise when the facts presented are unclear, contradictory, or open to different interpretations, making it difficult to determine the truth or reach a clear decision based on the available evidence.
