United Kingdom House of Lords Decisions

Earl of Halsbury—This is an appeal from the judgment of the Court of Appeal directing a new trial in an action by the widow of a man employed in a coal mine of the defendants, who was killed, together with several others, by an explosion in the mine on the 14th December 1907. It is not now matter of debate that the explosion was caused by a blasting operation, technically called a shot, which was required to remove a piece of rock which rendered it difficult to enlarge the main haulage road of the mine for the purpose of putting in some electric wires required therein. There are certain rules which have the force of a statute applicable to this colliery, and among them are rules applicable to the main haulage roadway and to dry and dusty parts of the mine when blasting operations are required. The place where the operation in this case was performed is both dry and dusty, and it is the main haulage roadway of the colliery. The rules in such cases require that only a particular class of explosives should be used; that within a certain distance the intended site of the explosion should be made wet artificially if it is not already wet naturally (which this place was not); that with some special exceptions the men should be withdrawn, and that the shot should be fired by a particular man who should be appointed specially for the purpose, and the shot selected for blasting should be selected by the manager of the mine, who should also see that the proper explosive material was brought into the mine for use. Further, to ensure the proper material being used, as I presume that he cannot be supposed to have sufficient chemical knowledge himself, he is protected if a properly signed certificate by an authority recognised by the rules certifies the genuineness of the authorised explosives. The work in respect of these electric wires began somewhere about July or August before the explosion on the 14th December. The cause was tried by Channell, J., on the 29th July 1908, and it was found that the cause of the explosion was the firing of a shot in a dry and dusty part of the mine; that it was fired in a prohibitive area where certain precautions were required to be taken, none of which were taken; and further, there was evidence that gunpowder was found in two holes bored for the purpose of being fired, and evidence was given rendering reasonably certain that the explosion itself had been caused by gunpowder, a prohibited explosive. It was further found that a man named Watkin Evans, who was seen boring the hole which was to be blasted, gave an order to a man named Miles, a collier, who in consequence fetched two pounds of gunpowder and brought it to his house the day before the explosion. Under these circumstances, which obviously called for
