Speaking to reporters after the session, Speaker Vladimir Seks said the proposed agenda contained 60 items, including 12 laws that were to be adjusted to EU standards.
By the end of this year's sitting, the parliament is expected to adopt 55 laws that are adjusted to EU legislation, Seks said.
After the summer recess, the parliament will hold another session before it is dissolved ahead of the start of the election campaign, Seks said.
The session is expected to start in mid-September and last until the first half of October, he added.
Seks said that before last Saturday's elections for the new leader of the Social Democratic Party (SDP), agreement had been reached with SDP officials that the party's new president would take the seat of chairman of the national committee monitoring Croatia's EU accession talks, previously held by the former SDP leader, the late Ivica Racan.
Seks said that it was up to the SDP to decide who it would nominate for that post, and the parliament would make a final decision.
The Sabor Speaker said that the parliamentary leadership today described as inappropriate recent statements by Party of Rights (HSP) deputy Ruza Tomasic that some parliamentary representatives were on the pay-roll of drug dealers.
"The Sabor Presidency concluded that such statements harm the dignity of the parliament and its deputies, and that MPs should not make such allegations without evidence," Seks said.
He also congratulated the new SDP leader, Zoran Milanovic, saying that his election was obviously the result of a need for changes and new people in the party.
Asked to compare Milanovic and HDZ leader Ivo Sanader, Seks said that it was too early to comment on differences between the two.
"Milanovic has won the trust of SDP deputies, but his platform and the way he deals with real, hard politics is yet to be seen. There are no scandals surrounding him, but his statements are yet to be tested in the political arena," Seks said.
