He returned to Aberystwyth as an Assistant Lecturer for two years before gaining a Lectureship at the London School of Economics in 1931 and then a Readership at the University of Birmingham in 1936. He also acted as a Visiting Professor at The Hague Academy of International Law in 1937. In 1940 he returned to Aberystwyth as Professor of Law and Head of Department, succeeding his former teacher T. A. Levi. He held these positions until his retirement in 1970, serving also for a time as Vice-Principal of the institution. He was President of the Society of Public Teachers of Law in 1955-6, was deacon of his chapel and Chairman of the Bench of Magistrates for many years. In 1970 he was awarded an O.B.E. for his services to legal education.
In 1952 Llewelfryn married Mary Thomas (1915-2013), the sister of Amy Parry-Williams. They had one daughter, Lynn, and two sons, Huw and Tomos. Mary played an important part in fostering the atmosphere of the Department during her husband's tenure as Head. This atmosphere was marked by openness and support, both for students and for the young members of staff attracted to begin their professional lives at Aberystwyth, many of both categories subsequently going on to have eminent careers. Llewelfryn was regarded with genuine and lasting affection, and the breadth of his vision attracted students to Aberystwyth from a range of Commonwealth countries. He taught a wide range of subjects at times when the Department was pressed for staff and whilst his interest in International Law had been important and had spawned publications, he also developed an expertise in Constitutional and Administrative Law. His journal articles included his published Presidential Address to the SPTL in which he stated his belief in a liberal, rather than narrowly professional, university education for lawyers. He also edited Jenks's Book of English Law in 1953. But it was for his leadership of the department with which he was, for a time, almost synonymous, and the ethos of generosity, care and encouragement which he created within it that he will be best remembered.
Llewelfryn Davies died in Aberystwyth on 6 April 1981 and his ashes were interred at Capel Nonni, Llanllwni.
