MPs of the two parties said that the bill sent by the Ivo Sanader cabinet to be discussed under urgent parliamentary procedure would undermine Croatia's financial sovereignty.
They also insisted that the bill be discussed under regular procedure.
Pero Kovacevic of the HSP assessed that the bill would prevent the possibility to audit the ownership transformation and privatisation of Croatian banks which he said were owned by foreigners.
We allocated 15 billion euros for the financial rehabilitation of banks. They were sold for one billion and now their value is 40 billion euros. Irregularities in bank privatisation have not been entirely dealt with, Kovacevic said.
Financial Ministry State Secretary Ante Zigman refuted the criticism from the HSP and the SDP, claiming that the proposed bill would enhance legal security, strengthen the capital market and the entire financial system and facilitate cross-border transactions.
Later in the day, members of the parliament discussed amendments to three energy sector laws - the energy act, the electrical power market act, and the act regulating energy activities.
Clubs generally supported the amendments adjusting the Croatian legislation to the European Union's standards in this sector.
They also supported a final bill regulating the transport of dangerous substances.
MPs suggested that it would be better to transport dangerous substances mainly by rail and that road transportation should be limited to exceptional cases.
Transport Ministry State Secretary Drazen Breglec said that in 2005, 6.33 million tonnes of dangerous substances had been transported in the country by truck, by rail and by inland waterways. This made up about eight percent of the overall transport of goods by the above-mentioned modes in Croatia.
The Sabor today expanded its agenda to include several new items such as a draft revised budget for 2007.
The revision of the 2007 budget will be discussed on Thursday.
