Appeal of interlocutory decisions to the superior court as a condition of fair trial

The article is devoted to the definition of «superior court» in the concept of criminal procedure appeal of interlocutory decisions. The novelty is in the fact that these decisions may be submitted by the same court that issued them. The author's opinion is that there is violation of the principle of judicial impartiality, incentivized to make certain decisions, because verifying of their legality, validity and motivation rests with colleagues who are in the same court. The legislator makes a mistake by joining two judicial authorities in the same court. Based on the analysis of the Convention on Human Rights, the International Covenant on Civil and Political Rights, the Russian legislation, scientific literature, jurisprudence and statistics it is proposed to impose a duty to review all criminal cases on the magistrate and district courts, turning regional courts into «full» courts of appeal.
