The president, who has to sign on the bill before it can become law, questions the aspects referring to parliamentary immunity which he considers interpretable as set by the bill.
The Parliament adopted the statute of MPs last week with 343 to 51 votes and 57 abstentions, amending a provision that had been ruled unconstitutional by the Constitutional Court.
The Constitutional Court on April 3 ruled a previous provision in the bill, which stated lawmakers in conflicts of interests would be suspended from parliamentary meetings, was illegal.
