obligation of insurance is imposed, with criminal penalty attached,
that the 'Trust should know beforehand with some degree of
accuracy what work it is required to do, that is as regards
the public; and equally so with regard to the Council, whose
satisfaction is demanded. On the other hand, it may be that the _
Council may prefer to do the work itself under its general powers, -
and at its own expense, rather than incur the delay or trouble of
a dispute and arbitration ; or it may consider such a course the -
more just, as, for instance, if damage 'were done to the road by a
heavy corporation steam roller ; or if the road fell into bad eon-
dition through some engineering mistake of the Council itsel{ -
all of which it would be hard on the Trust to be accountable for.
It would certainly be an additional hardship if the Trust were
responsible for the bad condition of 'the road, through the
misfeasance of the Council itself; but if there is the direct
absolute obligation to the public which is insisted on, this -
would necessarily follow, because no "direction" is given which
would exonerate the Trust. The position cannot be denied - that
according to the respondent there exist at the same time, in
respect of the same thing, two diverse, independent, and possibly -
conflicting jurisdictions. The Council under the Bristol Case (1),
and it has the sanction of Lord Halsbwry in the Dublin Case (2),
may repair or remake the road as it pleases and when it pleases,
regardless of the Tram Company's wishes; and the Tram
Company may, because by the hypothesis it must without any
direction from the Council, proceed to repair, whenever repairs,
as it ultimately appears in the opinion of a jury, have become
necessary. Even a direction by the Council not to repair would
not, if the respondent be correct, suffice to exonerate the Trust ;
nor even a mere prohibition as to certain materials, because
there is no general requirement to obey the Council's directions,
positive or negative. The requirement is to obey positive instruc-
tions as to materials and manner. So we may suppose two
co-ordinate bodies, neither directing the other, but in conflict as
to the materials and manner in which they shall respectively, at
their own individual several expenses, repair the public highway.
