One of the discretionary refusal reasons: Poor impulse control.

• A. Domestic incidents or patterns of concerning behaviour
• B. Substance misuse
• C. Poor impulse control
• D. Environmental ASB

Answer: (C)

Discretionary refusal decisions rely on risk-based judgment about whether continuing with a particular enforcement action is safe or appropriate. Poor impulse control describes a personal trait where an individual has difficulty restraining actions or emotions, leading to unpredictable and potentially dangerous reactions. In practice, this kind of trait is a clear red flag for safety—both for officers and the public—so it’s a key factor in deciding to pause, alter, or avoid a line of action and instead pursue alternatives or safeguards.

The other options describe situations or factors that typically indicate the need for action or intervention rather than a reason to refuse. Domestic incidents or patterns of concerning behaviour signal ongoing risk that warrants safeguarding or enforcement; substance misuse is a contributing factor to risk but not by itself a reason to refuse; environmental antisocial behaviour points to nuisance issues that usually require a response.
