Methodology in comparative legal research

By Yusuf Shaheen — A statement of practice

01

Abstract

What the paper covers

Comparative legal research is a craft, not a formula. This Working Paper sets out the methodological commitments that govern the Institute's comparative work — case selection, source discipline, the limits of comparison, and the conditions under which comparative claims are warranted.

Why method

Comparative legal research is easy to do badly. Done well, it grounds claims about legal practice in evidence that travels beyond a single jurisdiction. Done badly, it strings together superficial similarities and produces conclusions that do not survive contact with practice.

This Working Paper sets out the methodological commitments that govern the Institute's comparative work. It is a statement of practice, not a prescription for the field.

Case selection

Our case selection privileges depth over breadth. Each comparative project specifies its selection logic — why these jurisdictions, why this time-window — and notes the limitations that selection imposes on the claims that can be drawn.

Source discipline

Primary sources where available; secondary sources where necessary, with provenance noted. Translations are checked. Statutory text is read in its operational context, not in isolation. Judicial decisions are read with attention to procedural posture.

The limits of comparison

Comparison illuminates and obscures in equal measure. The same statutory phrase carries different work in different systems. The same procedural form rests on different institutional foundations. Our comparative work foregrounds these limits rather than papering over them.
