The vote is scheduled for late in the evening, including on a piece of legislation on tax-certified cash registers, one of the key legislative motions of the current National Assembly session.

The bill, which is to introduce a system of cash registers connected directly to the national revenue service at the start of next year, is part of the government's efforts to curb the informal economy by making it harder for businesses to cheat on retail revenue.

MPs will also vote on a bill on organ transplants envisaging a monitoring system for transplant patients following the procedure, and on changes to the act on waters.

The latter is the result of the Environment Ministry's efforts to overhaul water management after last year's series of extensive floods. If passed, the changes will introduce a new Water Management Directorate and extend the transitional period for water use permits issued in 2014 and 2015.

The parliament is also expected to pass changes to the environment protection act that remedy shortcomings in provisions governing environmental permits. The motion is related to the Lafarge Cement plant in Trbovlje.

The end of the session marks the start of summer recess, although MPs are planning to convene for at least one emergency session before breaking off for the holidays.
