“In particular, a highway authority are under a duty to ensure, so far as is reasonably practicable, that safe passage along a highway is not endangered by snow or ice.”
“In a case, therefore, where the damage complained of has been caused not by a failure to maintain the highway but by something done by the highway authority, or for which the highway authority have become responsible (c/f Sedleigh-Denfield v O'Callaghanhttp://www.bailii.org/cgi-bin/redirect.cgi?path=/uk/cases/UKHL/1940/2.html[1940] AC 880 and see section 130(3) of the 1980 Act), liability continued after 1961 as before, to be determined by the common law principles of negligence or, as the case may be, public nuisance. It is only where the alleged liability arises out of a failure "to maintain" the highway that the section 41(1) duty and the section 58(1) defence come into play.”
“In my opinion, an occupier of land “continues” a nuisance if, with knowledge or presumed knowledge of its existence, he fails to take any reasonable means to bring it to an end, though with ample time to do so. ”
