PKR strategy director Rafizi Ramli said the call by a senior election officer in Sabah to re-register voters was further proof that the electoral system was flawed.
"I want to hear what the Election Commission chairman and his deputy have to say to this," he said.
Rafizi was commenting on the on-going Royal Commission of Inquiry on illegal immigrants in Sabah where the state's election director Datuk Md Idrus Ismail, when giving evidence, said the 13 million voters nationwide must be registered again as the electoral roll was tainted.
Rafizi, who is also Pandan MP, said this clearly showed that the organisation and execution of the 13th general election was highly questionable.
"There are many questions being raised on the ballot paper, the ballot boxes and the indelible ink.
"All these have resulted in the public losing confidence in the electoral system and in the conduct of the polls," he told reporters at the PKR headquarters in Tropicana, Petaling Jaya.
At the same event, PKR candidate for the Tapah parliamentary seat K. Vasantha Kumar said the fact that the presiding officer at the Tapah seat was a MIC division chief is also grounds to question the contest.
"According to election laws, a presiding officer must not hold any political positions but this was not the case in Tapah." he told The Malaysian Insider.
He has also listed, among others, the murder of his former political aide, K. Murugan, 36, as another reason to petition to nullify the result.
Vasantha lost to Barisan Nasional's Datuk M. Saravanan, a MIC vice-president.
He claimed that three ballot boxes which contained early and postal votes for the constituency were removed three days before polling day from the Tapah police station.
"The boxes are for the Tapah parliament seat as well as for the Chenderiang and Ayer Kuning state seats which amounted to 2,195 votes," Vasantha said.
He said that his campaign workers who happened to be at the station questioned the removal of the boxes but were told not to interfere.
"There were six people who loaded the boxes onto a lorry." he said.
Vasantha alleged that the Tapah police station chief had also allowed for the boxes to be removed.
"We have facts and photographs to prove our case."
According to election law, the boxes can only be taken from the police station on polling day. – July 5, 2013.
