Research Themes
Research Summary

My research interests are principally in legal history, particularly early-modern English legal history. I have particular interests in the history of common-law reasoning and its interaction with legal theory as well as the relationship between texts and legal practice. As part of the latter I work on book history.

Recent work has focused on the relationship between early-modern legal theory and legal practice/reasoning and has led to two book chapters published in 2016:

  • 'Developing a Prerogative Theory for the Chancery: the French Connection', forthcoming in the proceedings of the 2013 British Legal History Conference and awarded the David Yale Prize by the Selden Society; 
  • 'The Role of Rules: Legal Maxims in Early-Modern Common Law Practice and Principle'. 

I am currently working on a variety of legal history projects:
  • several articles and chapters on the dissemination of legal knowledge in early-modern England and especially English legal printing in the reign of Charles I;
  • several articles as part of a large project concerning the court of Star Chamber. Part of this research (concerning the theory and practice of Star Chamber as a court of criminal equity) is supported by a British Academy/Leverhulme Trust Small Research Grant;
  • an investigation of the idea of common opinion as a source of law from the thirteenth to sixteenth centuries.

I also work on topics in modern property law. Recent work in that field covers:
  • the certainty of term requirement in leases (published in the 2015 Cambridge Law Journal);
  • understanding the common law forfeiture rule in succession law (forthcoming in Haecker and Mitchell (eds), Current Issues in Succession Law (Hart)).
