What does incompliant mean?
Incompliant is an adjective meaning that someone or something fails to follow a rule, instruction, standard, or lawful requirement. It may describe deliberate resistance, such as a person defying an authority, or an objective failure to meet a regulatory condition, such as a business operating without required approval. The word is most common in legal, governmental, institutional, and safety-related contexts, where precision matters. Its negative force is stronger than that of a simple neutral description of a mismatch: an incompliant person is actively or persistently failing to obey, while an incompliant system or organization is not meeting an applicable standard. Although “noncompliant” is now more frequent in general use, “incompliant” has a more formal and occasionally more accusatory tone. The related noun “incompliance” names the condition or conduct itself.
adjectiveNot complying with a rule, requirement, authority, or request; unwilling or unable to follow prescribed instructions or standards.
- Failing or refusing to comply with a rule, requirement, authority, instruction, or standard.
"The regulator warned that the company had become incompliant with safety requirements."
"The witness was accused of being incompliant with the investigation."
"Repeated warnings were issued after the tenant remained incompliant with the building regulations."
Incompliant means “not playing by the rules”—and it is more pointed than its plainer cousin, “noncompliant.”
