It is not the case of the appellant that Tarsem Singh had incurred any of the disqualifications mentioned therein. No other provision of law in the Act or in any other law was brought to our notice disqualifying him from exercising his vote. The right to vote being purely a statutory right, the validity of any vote has . to be examined on the basis of the provisions ol the Act. We cannot travel outside those provisions to find out whether a particular vote was a valid vote or not. In view of s. 30 of the I 950 Act, civil courts have no jurisdiction to entertain <,Jr adjudicate upon any question whether any person is or is not entitled to register himself in the electoral roll in a constituency or to question the illegality of the actiqn taken by or under the authority of the electoral registration officer or any decision given by any authority appointed under that Act for the revision of any such roll. Part III of the 1950 Act deals with the preparation of rolls in a constituency. The provisions contained therein prescribe the qualifications for being registered as a voter (s. 19), disqualifications which disentitle a person from being registered as a voter (s. 16), revision of the rolls (s. 21), correction of entries in the electoral rolls (s. 22), inclusion of the names in the electoral rolls (s. 23), appeals against orders passed by the concerned authorities under ss. 22 and 23 (s. 24). Sections 14 to 24 of the 1950 Act arc integrated provisions. They form a complete code by themselves in the matter of preparation and maintenance of electoral rolls. It is clear from those provisions that the entries found in the electoral roll arc final and they are not open 10 challeirige either before a civil court or before a tribunal which r,onsiders the validity of any election.
