The commission could vote on its final report on October 12, according to the commission's chairman Ringolds Balodis.
The commission previously approved MP Artuss Kaimins' proposal to include in the final report a list of persons "morally responsible" for the tragedy including former Prime Minister Valdis Dombrovskis, former economy ministers Artis Kampars, and Daniels Pavluts, plus other government officials.
As reported, 54 people died and several dozens were injured as a "Maxima" supermarket in Riga's Zolitude neighborhood collapsed on November 21, 2013. The Riga supermarket tragedy has become the largest loss of life since the restoration of independence in 1991.
The Saeima investigation is separate from the official investigation into the disaster and is purely advisory.
So far no-one has been convicted of legal responsibility for the loss of life.
