Now that the statutes formerly ascribed to Winchelsey and Reynolds have been shown to derive from other sources, those of John Stratford, issued after the Second Council of London (1342), are seen to stand out as the most significant body of provincial legislation in the later Middle Ages. Their relative importance is enhanced by the paucity of such legislation in this period in comparison with the considerable volume produced in the course of the thirteenth century.

On investigation, Stratford's constitutions appear significant in the corpus of medieval ‘administrative’ canon law. Not only do they show signs of the friction existing between the lay and ecclesiastical jurisdictions and experienced both by Pecham and Winchelsey, but also of the recurring clerical concerns, frailties of conduct, and malpractices of church courts and officials alike. Provincial legislation springs partly from local imperfections, and partly from more general circumstances. Political considerations may have been critical in the decision to issue constitutions. There is justification, therefore, for first examining the political context in which these constitutions arose.

By 1340, Stratford's position was ambiguous and unenviable. Bound by his chancellorship to ensure the observance of recent royal statutes, he could see that these very statutes placed his clergy under an intolerable and exceptional burden of taxation, in direct contravention of the bull Clericis Laico. Tenths which produced growing resentment were taken in 1338 and in 1340, and a ninth imposed at the same time caused an impassioned outburst from Adam Orleton, Stratford's old political rival.
