What process allows an agency to compel individuals to provide evidence or testimony?

The process that enables an agency to compel individuals to provide evidence or testimony is investigation. During an investigation, an agency gathers information relevant to its regulatory responsibilities, often utilizing various powers granted to it by statutes. This includes the ability to issue subpoenas, which can require witnesses to testify and produce documents relevant to an inquiry.

Investigation serves as a crucial function in administrative law because it underpins the ability of agencies to enforce regulations, ensure compliance, and address violations. The evidence and testimonies gathered during this process inform decision-making and can lead to enforcement actions if necessary.

Adjudication refers to the formal resolution of disputes and the rendering of decisions based on evidence presented in a hearing, not the process of gathering information. Rulemaking, on the other hand, involves the creation of regulations through a formal process, and while it may require input from the public, it does not involve the compelling of testimony or evidence. Negotiation typically involves discussions between parties to reach a mutually agreeable outcome, which does not include the authority to compel testimony or evidence from individuals.
