Unfortunately, in the whole of this election petition, the expression to the effect that, the result of the election, insofar as it concerns the Returned Candidate, has been materially affected by the non-submission of Form A to the Chief Electoral Officer, does not find a place. Only in paragraphs 8, 9 and 10 of the election petition, the expression "materially affected" has been vaguely employed and the said paragraphs are extracted below: “8 . . .
