Judiciary Lobbying

Judicial Lobbying: The Politics of Labor Law Constitutional Interpretation
Matias Iaryczower, Pablo Spiller, Mariano Tommasi – NBER #11317

This paper links the theory of interest groups influence over the
legislature with that of congressional control over the judiciary.
The resulting framework reconciles the theoretical literature of
lobbying with the negative available evidence on the impact of
lobbying over legislative outcomes, and sheds light to the
determinants of lobbying in separation-of-powers systems. We provide
conditions for judicial decisions to be sensitive to legislative
lobbying, and find that lobbying falls the more divided the
legislature is on the relevant issues. We apply this framework to
analyze supreme court labor decisions in Argentina, and find results
consistent with the predictions of the theory.
