R. v Comeau and Section 121 of the Constitution Act, 1867:\nFreeing the Beer and Fortifying the Economic Union
Bibliographic record
Abstract
A recent decision from the New Brunswick Provincial Court may have significant implications for Canada's constitutional structure. R. v. Comeau held that s. 121 of the Constitution Act, 1867, the constitution's internal free trade provision, prohibits both interprovincial tariffs as well as non-tariff trade barriers. In doing so, the court departed from a line of precedents holding that s. 121 prohibits only the erection of outright tariffs or duties on interprovincial trade. Ultimately the court held that s. 134(b) of New Brunswick's Liquor Control Act, which effectively prohibits the possession of all but small quantities of liquor purchased out of province, constituted a non-tariff barrier in contravention of s. 121. The Supreme Court of Canada recently granted leave to appeal. The author argues that the judge was correct in holding that s. 121 should extend at least to some non-tariff barriers. Yet the decision leaves important questions unanswered, including how s. 121 can be reconciled with provincial regulatory authority how a construction of s. 121 should be informed by the constitutional principles of democracy and federalism, and how doctrine can be developed so as to appropriately distinguish between permissible and impermissible non-tariff barriers. The author proposes a framework that aims to reconcile the trial judge's analysis with these additional considerations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
