Where the court or the clerk of petty sessions is satisfied that the applicant had reasonable cause for failing to serve the notice required by paragraph 2, the application may be considered notwithstanding that the provisions of that paragraph have not been complied with, if the court or, as the case may be, the clerk is satisfied that the sub-divisional commander or the district council does not object, and such an application shall not, by reason only of that failure, be treated as not having been duly made.
