Prior conciliation process was regulated, from the mercantile codification (1829-30) in substantive and procedural bodies. It was a prior and mandatory requirement to be able to initiate the declarative process the attempt of the conciliation and that was not proving in the same agreement «or positive result» between the legitimized persons, future parts contenders. His obligation was based on the historical -juridical tradition from which it went on to the procedural Codes that kept her obligatory until 1984, the reform of the LEC, it makes her voluntary for the civil process. The LEC 2000 did not regulate the prior conciliation and demonstrated for the first time his desire of «carrying, moving, or banish» the prior conciliation -regulated in the LEC of 1881 and in force until July 22, 2015 to a future Law of the Voluntary Jurisdiction (the current Law 15/2015 of 2-7-2015, and in force since July 23) what proves to the first censurable sight since the previous conciliation has little to see with the purpose and the foundation to which it answers the voluntary jurisdiction. It is censurable also that the LEC 2000 regulates, the contemporary procedural conciliation -under the obligatory direction of the Judge, initiated the process- in the ordinary judgment, silence her in the verbal judgment and that was excluding the regulation of the voluntary previous conciliation -with clear procedural foundation- in the acts before the process before the preliminary proceedings. They should be had regulated together by his similar legal regime and effects. The in force LJV of July 2, 2015 is apart of the historical tradition and regulates only the prior and voluntary conciliation to the civil declarative process; without reference to the contemporary conciliation LEC, not to the prior mandatory one on the civil object derived from the crime that budget to initiate criminal proceedings in the crimes subject to the regime of private procedure which refers, without regular, the LEC.
