NDP leader Trent Wotherspoon is critical of a decision to allow former Deputy Premier Don McMorris back into the SaskParty caucus.
McMorris resigned from caucus and cabinet last summer after a drinking and driving conviction.
Wotherspoon says it sends a bad message to the public.
He says it reflects poor judgement by the premier and trivializes the wrong-doing.
Premier Brad Wall says McMorris has paid a price publicly and personally and caucus voted for his return.
Wall says his government has introduced significantly stiffer penalties to change attitudes about drinking and driving in Saskatchewan.
He adds a publicity campaign has been launched to stop drinking and driving.
Premier Wall says drinking and driving fatalities are down 13 per-cent but more will be done to change attitudes.
