. On February 23, 1909, Prime Minister
Wilfrid Laurier appointed Anglin to the Supreme Court of Canada following the retirement of Justice
James Maclennan earlier on February 13. Laurier's judicial appointments during this period reflected a blend of merit, political patronage, and governmental interest rather than a consistent commitment to the long-term development of the Court. The politicized nature of such appointments, and the Court's use as a political instrument, contributed to what historians Snell and Vaughan have described as an era of institutional decline during the
Fitzpatrick Court era. Nevertheless, they note that Anglin stood out among Laurier's appointees for his professional competence and prior judicial experience. Anglin quickly established himself as an active and independent member of the Court, authoring opinions in significant cases soon after his appointment rather than merely concurring with his colleagues. In 1910, without notifying the other justices, he submitted to the government a draft bill proposing amendments to the
Supreme Court Act to permit the appointment of
ad hoc judges. The proposal was not acted upon at the time, though the idea was adopted in 1918. In 1917, Anglin joined Chief Justice
Fitzpatrick, Minister of Justice
Charles Doherty, and politician
Charles Murphy in urging Prime Minister
Robert Borden to advocate for
Irish home rule within the British Empire. Anglin's judgment in
Re Gray (1918), which upheld Parliament's delegation of broad legislative powers to Cabinet under the
War Measures Act during the First World War, was published in advance of the
Supreme Court Reports in both The
Toronto Globe and the
Canadian Law Journal. Under Justice
Pierre-Basile Mignault, the Supreme Court began treating the
Quebec Civil Code with a firm judicial pattern of treatment emphasizing the distinct nature of the
Civil Code and refusing to apply common law principles. Anglin's concurrence with Mignault and the other Quebec judge
Louis-Philippe Brodeur allowed decisions such as
Desrosiers v The King (1920) and
Curley v Latreille (1920) to become authority for adjudicating civil law cases without the use of English common law traditions. In 1923, Anglin was selected as Canada's nominee to the newly formed
International Court of Justice at The Hague, though he was ultimately not chosen for appointment.
Chief Justice of Canada appointed Anglin to the role of Chief Justice over
Lyman Duff. On May 1, 1924, Chief Justice Louis Henry Davies died at age 78. Although he had intended to retire in 1921, he remained on the bench amid a dispute over the terms of his pension. Following his death, Prime Minister
William Lyon Mackenzie King appointed Anglin as the seventh Chief Justice of Canada on September 16, 1924. In keeping with custom, Anglin was sworn into the
Imperial Privy Council in 1925 following his elevation to Chief Justice. Anglin was not King's preferred candidate for Chief Justice. The prime minister had repeatedly offered the position to the distinguished Quebec lawyer
Eugène Lafleur, even enlisting Governor General
Lord Byng to persuade him, but Lafleur declined each time. At the time of appointment, Anglin was the third most senior member of the Court. He was elevated over Justice
John Idington, whose mental capacity had significantly declined and who was later compelled to retire after Parliament introduced a mandatory retirement age of 75 in 1927. Also senior to Anglin was Justice
Lyman Duff, widely regarded as the Court's most capable jurist, but his earlier collaboration with
Robert Borden's Conservative government and struggles with alcoholism made his appointment politically untenable. As Chief Justice, Anglin was an outspoken critic of the
Judicial Committee of the Privy Council serving as Canada's final court of appeal. In a letter to Prime Minister Mackenzie King, he wrote that "my Canadianism" led him to believe that "should finally settle our litigation in this country. If we are competent to make our own laws, we are, or should be, capable of interpreting and administering them," concluding that "it would be best to terminate all appeals to London." In 1925, Anglin publicly criticized
Lord Haldane of the Privy Council for his reasoning in
Russell, which had upheld the
Canada Temperance Act on the ground that drunkenness in Canada constituted a national disaster warranting emergency intervention. Anglin's remarks, delivered in a judgment that rejected Haldane's expansive reading of federal power, were applauded by the
Canadian Bar Review. In the
Persons case, Anglin held that women were not "qualified persons" for the purpose of appointment to the
Senate of Canada. In his decision he noted the decision to permit the appointment of women to the Senate was a political decision for parliament, and judges should remain focused on the language of the Constitution. The decision was overturned on appeal by
Lord Sankey of the Privy Council, who held that the term could be read broadly to include women and articulated the now-foundational
living tree doctrine doctrine of constitutional interpretation, under which the Constitution is "capable of growth and expansion within its natural limits." In subsequent cases, however, Anglin interpreted this principle narrowly. During the early decades of the Supreme Court, it was customary for each justice to write individual reasons for judgment rather than issuing joint opinions. Combined with the frequent dismissal of appeals due to evenly divided votes, this practice made it difficult to establish clear precedents or discern a coherent judicial philosophy. As a result, the Court often resolved disputes by applying existing legal principles rather than developing new ones. Under Chief Justice Anglin, this individualistic approach began to change. During the 1920s, members of the
Canadian Bar Association increasingly called for the Court to issue single majority judgments to clarify the law. Anglin supported this reform, persuading his colleagues to write unified decisions. Where consensus existed, one justice would draft and circulate a majority opinion for review and comment. However, if there was not initial agreement, justices would draft their own individual drafts which would be exchanged. By 1929, Anglin's health had begun to decline, and he took an extended leave of absence. That autumn, Prime Minister King privately described him as "failing, [and having] lost all his brightness." Anglin continued to take annual leaves throughout the early 1930s. In 1933, after a private conversation with King about retirement, the former prime minister urged him to step down. Eventually the government threatened to initiate a formal inquiry into his health and capacity to continue in office. Under mounting pressure, he resigned in February 1933, effective at the end of the month. On March 2, 1933, just three days after his retirement at the age of 67, Anglin was found dead. == Personal life ==
