ISSUE

Can an individual request the opportunity to provide an approved screening device ["ASD"] sample at a police station or at a later time after having refused to comply with a roadside ASD demand?

BRIEF ANSWER

Individuals can change their mind about complying with an ASD demand after an initial refusal if their reconsideration is part of the "same transaction" as their refusal. If an individual requests the opportunity to provide a sample as part of the same transaction as their refusal, the actus reus of the refusal offence cannot be established.

The length of time of such a transaction is context dependent but it is the same time window during which a police officer can lawfully compel a breath sample as set out by the statutory immediacy requirement. The statutory immediacy requirement sets out that an ASD must be provided immediately, subject to the operational time it takes an officer to ready the equipment and instruct the suspect.
