The contribution evaluates the application of the Roman law principles of the trial to the current Slovak procedural codes – Civil Dispute and Civil Non-dispute Code. It focuses on finding out whether those principles have been taken into our regulations and, if so, in what form. It is an interesting probe into both – in the Roman procedural law and in the current form of the Slovak civil process, especially with regard to the fact, that Roman law sought justice, decency and morality in procedural and substantive law as well. What is currently the main interest of the Slovak court proceedings? Is it a searching for justice, or have other priorities prevailed? Even in creating these (relatively) new Codes, the traditional struggle of natural and positive law was fought. The article evaluates the outcome of this fight (quite critically).
