Generally speaking there are 5 basic constitutional issues that are commonly engaged in a
successful defence of drinking
and driving cases: «arbitrary detention» (s. 9 of the Charter), «unreasonable
search and seizure» (s. 8 of the Charter), «right to counsel» (s. 10 (b) of the Charter), the «right to be informed promptly of the reasons for your detention» (s. 10 (a) of the Charter)
and the «right to be tried within a reasonable time» (s. 11 (b) of the Charter).
