Abstract
The April amendment introduced a new extraordinary measure of appeal to the criminal procedure, i.e. complaint against the appellate judgement revoking the first instance ruling for reconsideration. It is an institution referring to the civil procedure, which is totally alien to the criminal proceedings, especially with regards to extraordinary measures of appeal. The publication discusses the grounds for complaint, its filing and processing procedure. It critically reviews the adopted legislative solutions, though positively evaluates the idea itself , which has been distorted by defective solutions and numerous ambiguities to be coped with by the practice.
