s 15 Questions of foreign law to be decided by judge.
Where, for the purpose of disposing of any action or other matter which is being tried by a judge with a jury in any court in England and Wales, it is necessary to ascertain the law of any other country which is applicable to the facts of the case, any question as to the effect of the evidence given with respect to that law shall, instead of being submitted to the jury, be decided by the judge alone.
