When an advocate becomes aware that their client intends to provide false evidence, they must balance their duty to the client with their duty to the court and justice system:
The advocate should advise the client against submitting false evidence, explaining the legal and ethical consequences.
If the client insists, the advocate must not knowingly present false evidence or assist in any deception.
The advocate may withdraw from the case if possible without breaching confidentiality.
In some jurisdictions, if withdrawal is not possible and false evidence is imminent, the advocate may have a duty to inform the court to prevent miscarriage of justice.
The advocate’s paramount duty is to uphold the integrity of the judicial process while maintaining client confidentiality as far as ethical rules permit.
Failure to adhere to these standards can lead to professional sanctions and harm to the justice system.
