Software company Helmes has submitted its analysis of the delays experienced on election night, citing human error in database configuration.
The electoral committee will also hear testimony from independent experts within the week before making a decision about imposing contractual penalties, said electoral committee chairman Heiki Sibul.
Helmes says the hour-long delay was caused by the fact that the changes in he election results report began lagging and did not refresh at the required speed.
In the report, Helmes portrayed its response as efficient, and said it made sure that the measures taken would not affect the functioning of the basis system, the election information system.
The cause was human error in the database configuration. Testing was only conducted at 40 percent system capacity, so it was not revealed.
"Yet no signs emerged pointing to the need for further testing," said Helmes quality control head, Meelis Lang.
Helmes expressed regret for the incident and said it is ready to compensate material damage caused by the delay.
