Extending rights` reach, Mathews, Jud (associate Professor Of Law, Pennsylvania State University School Of Law)

In every constitutional system with judicially enforceable constitutional rights, courts must make choices about whether, when, and how to give those rights horizontal effect. This book is about how different courts make those choices, and about the consequences that they have. The doctrines that
courts build to manage the horizontal effect of rights speak to the most fundamental issues that constitutional systems address, about the nature of rights and of constitutionalism itself. These doctrines can also entrench or enhance judicial power, but in very different ways depending on the legal
system.
