DIP said that it checked reports from those two polling stations and that it had had no reason to suspect them because they had been written and signed properly.
It added that it subsequently asked voter committees to submit reports on their work which would be published later.
GONG informed DIP that slips from voter lists at one polling station in Capljina and one in Orasje stated that two persons, which GONG claims are dead, had voted.
GONG also said that there were persons listed at those two stations who told it over the phone that they had not gone to the polls.
GONG told a news conference earlier today that based on press articles and calls from citizens, it investigated the voting process and concluded there existed serious indications of abuse of electoral rights at polling stations for Croatians residing in Bosnia at the January 2 presidential elections.
For that reason, GONG has pressed charges against unidentified perpetrators with the State Prosecutor's Office.
GONG also highlighted the high number of newly registered voters at polling stations in Bosnia, pointing to the very likely possibility of double voting.
DIP said that even if voter committees at those polling stations were guilty of wrongdoing, the effect on the final election result was negligible.
For the January 16 run-off, DIP has appointed new committees for those stations and those on which some members were municipal or city councillors of the Croatian Democratic Union party, whose candidate Jadranka Kosor is running for president.
GONG announced its mobile teams would step up the monitoring of the vote in Bosnia. The Organisation for Security and Cooperation in Europe donated GONG 20,000 euros to monitor the vote in Bosnia in the first and 21,000 euros in the second electoral round.
The State Prosecutor's Office confirmed receipt of the charges filed by GONG and that it was collecting information about the case.
