Rh meaning. Even where 'if' seems required to qualify 'when' (which by itself might be taken to exclude the possibility of the event's never happening at all), 'if' and 'when' are clearly not coordinate, though both are subordinate to the main sentence: 'if and when he comes, I will write' means 'if he comes, I will write when he comes', or 'when he comes (if he comes at all), I will write', and the 'if' clause, whether parenthetic or not, is subordinate to the whole sentence 'I will write when he comes'. Our Gladstone instance below differs from the rest: 'when' with a past tense, unqualified by 'if', would make an admission that the writer does not choose to make; on the other hand, the time reference given by 'when' is essential; 'on the occasion on which it was done (if it really was done) it was done judicially'. The faulty coordination may be overlooked where there is real occasion for its use; but many writers seem to have persuaded themselves that neither 'if' nor 'when' is any longer capable of facing its responsibilities without the other word to keep it in countenance.
