A statement from the presidential office said Vejonis had submitted proposals to the 13th Saeima to improve the legislative process.
"In order to raise the quality of the drafting of laws and to promote public confidence in state power, the President encourages making changes to the Saeima's Rules of Procedure," the statement said.
The President proposes that when submitting proposals for a new draft law, both the grounds for the proposals and information on consultations that have already happened should be provided in writing.
Vējonis also repeated a previous call for substantive changes to draft laws not to be permitted immediately before the third and final readings of bills in parliament, and instead to ensure that the first and second readings are when this process should take place.
"This would avoid hasty last-minute solutions that have a high potential for error," the President said in a 5-page letter to the Saeima's legal affairs committee.
In his letter to the 13th Saeima, the President said that he had repeatedly called on the Saeima to improve the legislative process and improve the quality of laws - though whether they act upon his proposals this time around remains to be seen.
