Why this article is proposed
Alberta has a working executive today: a Premier who leads a Cabinet, a Lieutenant Governor who represents the Crown, and ministers accountable to the Assembly. Most of how this works is convention plus the Executive Council Act and the Constitution Act, 1867. This article would move the core rules into a written provincial constitution, with explicit limits and an explicit emergency-powers framework.
What it would change
The structural picture stays close to what Alberta already has: a Premier confirmed by the Assembly, ministers chosen by the Premier, and confidence as the test for continuing in office. New entrenchment includes a thirty-day cap on emergency powers (renewable by the Assembly), explicit prohibitions on political direction of police and judiciary, and a constitutional oath of office. Two clauses, the power to represent Alberta in international relations and the power to direct responses to federal laws deemed unconstitutional, reach past what a province can do under section 45 of the Constitution Act, 1982. Both are flagged in the section notes.
The legal basis
Defining the provincial executive is a use of Constitution Act, 1982 s.45 (the legislature of each province may exclusively make laws amending the constitution of the province). The office of the Lieutenant Governor is protected by s.41(a) and cannot be removed by a provincial constitution alone; the section that vests executive power does not name the Lieutenant Governor, so a careful read is needed to confirm the article describes responsible government rather than displaces the Crown's representative.
Open questions
Two questions for Albertans: should a written provincial constitution attempt to assert any provincial role in international relations, knowing that the assertion is at most a negotiating position rather than a self-executing rule, and should the executive oath continue to include allegiance to the Sovereign, which would require unanimous constitutional amendment to remove.
