McGhee v National Coal Board
1972 English tort law case
McGhee v National Coal Board [1972] UKHL 7, 1 W.L.R. 1, is a leading tort case decided by the House of Lords. The Lords held that where a breach of duty has a material effect on the likelihood of injury then the subsequent injury will be said to have been caused by the breach. This approach was taken to resolve injustice arising from the orthodox 'but for' test for factual causation. Otherwise, under the 'but for' test, multiple potential causes of harm would hold equal causal weighting, making it impossible to establish a greater than 50% probability of one cause.
