What two types of evidence are considered "prima facie" according to the CSL?

The correct choice identifies the two types of evidence classified as "prima facie" under the Comprehensive Sediment Law (CSL). Prima facie evidence refers to that which is sufficient to establish a fact or raise a presumption unless contradicted or disproven. In this context, a sample taken by an enforcement officer is a tangible piece of physical evidence that can directly link to an alleged violation or condition being assessed. Additionally, a laboratory report provides scientifically validated results that support findings from the sample, giving credibility and weight to the facts presented. Together, these forms of evidence are robust in establishing a preliminary case that can stand up to scrutiny.

Other options present various forms of evidence, but they do not carry the same level of establishment as prima facie. While a photograph and a witness statement can be useful, they may not provide direct, objective evidence in the way that an enforced sample and its corresponding lab report can. Similarly, while a financial report and an insurance document are important in other legal contexts, they do not directly tie to environmental or regulatory violations in the same way that a sample and laboratory analysis do. Therefore, the combination of a sample and a laboratory report is a reliable and recognized method of establishing the facts in cases relevant to the CSL
