Prosecutors balance the goal of convicting the guilty with the duty to protect the innocent by adhering to specific ethical and legal obligations that prioritize justice over mere conviction. Because the prosecutor represents the state, they hold a dual interest: securing convictions for criminal acts while ensuring the acquittal of the innocent.1
To maintain this balance, prosecutors are bound by the following principles:
- Disclosure Obligations: Prosecutors have an ethical and legal duty to disclose to the defense any information known to them that might exonerate the defendant or mitigate their punishment.1
- Fair Trial Standards: They must refrain from using trial tactics designed to secure unfair convictions and are ethically prohibited from prosecuting cases solely to advance their own political interests.1
- Discretionary Judgment: In many systems, prosecutors possess extensive discretion to determine if sufficient evidence justifies criminal proceedings. This allows them to decline prosecution for individuals who may be technically guilty under strict liability laws but appear morally innocent.2
- Protection of Rights: In various jurisdictions, prosecutors are responsible for ensuring that the guaranteed rights of the accused are protected throughout the investigative and trial processes.3
