If at the expiration of the time specified in the notice the occupier has failed to comply with the notice, a magistrates' court, if satisfied on complaint made by the authority that the wire is a nuisance to the highway, may order the occupier to abate the nuisance and, if he fails to comply with the order within a reasonable time, the authority may do whatever may be necessary in execution of the order and recover from him the expenses reasonably incurred by them in so doing.
If the local authority who are a competent authority in relation to the highway concerned are the occupiers of the land in question proceedings under this section may be taken against them by any ratepayer within the area of that local authority and the foregoing provisions apply accordingly in relation to him and to the authority as they apply in relation to an authority and to an occupier of land.
