What does firsthand knowledge refer to in the context of a petition?

Firsthand knowledge in the context of a petition refers specifically to the personal knowledge an individual has about the facts that are necessary to support the statements made within that petition. This type of knowledge is crucial because it ensures that the information presented is based on the individual's direct observations or experiences rather than secondhand accounts or assumptions.

This type of evidence tends to carry more weight when assessing credibility because it indicates that the individual has a direct connection or involvement with the matters at hand. Hence, the requirement for personal knowledge helps to establish the veracity of the claims made and supports the integrity of the petition and its underlying assertions.

The other options, while they may seem related, do not encapsulate the essence of firsthand knowledge as it pertains to legal and formal settings like petitions. Public records may provide useful information, but they do not constitute firsthand knowledge since they are indirect sources. Similarly, information garnered from online sources or expert opinions lacks the direct personal experience aspect that defines firsthand knowledge.
