"We take no responsibility for the accuracy of the data nor for consequences they might have," commission chairman Josip Leko told the press.
He said the figures published by the newspaper did not correspond to the commission's figures, and that they came from a private collection which also mentioned former officials in whom the commission was, therefore, no longer interested in.
Leko said the newspaper had also published confidential personal data, such as officials and their children's savings and addresses.
He went on to say that the commission was expected to publish officials' complete declarations of assets on its own website soon, but added the parliament's technical service first had to provide a server and a special computer programme.
Leko said the commission would not be authorised to investigate who provided the data published by Jutarnji List, but wanted to state that the data was not official and had not come from the parliamentary commission.
Leko said that since February the commission had launched seven proceedings, establishing that in five cases officials had been in conflict of interest.
