On May 10, 2002, Mrs. Acosta's legal representative presented the first of the four incidental motions for annulment (incidentes de nulidad) filed in the course of these judicial proceedings. Specifically, this incidental motion requested annulment as of the order of April 19, 2002, for Mrs. Acosta to give a defendant's statement due to the accusation made by Peter Martínez. Part of the grounds cited in this incidental motion was that no defense counsel for María Luisa Acosta had been appointed.93 On May 13, 2002, the District Criminal Court Judge allowed María Luisa Acosta's accusation against Iván Argüello and others and officially authorized Mrs. Acosta's lawyer to represent her in the proceedings.94 c. Definitive dismissal of proceedings in favor of Peter Martínez, Peter Tsokos, and Charles Presida 51. On that same day, May 13, 2002, the District Criminal Court Judge handed down a judgment dismissing proceedings against Peter Martínez, Peter Tsokos, Charles Presida, and María Luisa Acosta because he considered that “there[was] evidence incrimin[ating] them as instigators or abettors because the file only contain[ed] an accusation, which [was] not enough to deduce criminal liability, because neither the National Police, nor the Prosecutor’s Office [had] produc[ed] any evidence from which criminal responsibility could be deduced.”95 He also ordered that Iván Argüello be imprisoned as the alleged perpetrator of the murder96 and he rejected the first incidental motion for annulment.97 52. On May 15, 2002, Mrs. Acosta's legal representative filed an appeal against that judgment.98. In the court order admitting the appeal, the District Criminal Court Judge ordered "the appellant to deliver to the Court secretariat the corresponding paper needed to record all the litigation,"99 that is to say, to provide blank paper for photocopying the judicial file. Mrs. Acosta's representative was notified of that order the following day.100 53. On May 22, 2002, Mrs. Acosta's representative filed an interlocutory appeal [recurso de reforma] against the Court order of May 17, 2002, due to the fact that an appellant could not be ordered to 91 Appendix 94.
