The aim of the book is to verify the constitutionality of the application of the Incident for the Resolution of Repetitive Demands (IRDR) within the scope of the special civil courts, as well as to identify the practical problems of applying the institute in the courts. These questions are extremely important, given that the introduction of this institute into Brazilian procedural law comes with the promise of speed and justice for mass claims. On the other hand, the proposal comes up against some resistance, since its standardisation, when confronted with the constitutional text and the current structure of Brazilian justice, exposes a series of problems - both practical and doctrinal - that simply cannot be ignored by the operator or legal scholar.
