42. The State presented various observations and asked the Court to assess these, in particular,
those regarding the transfer of the expert opinions to the present case, as well as in relation to the
testimonies rendered by affidavit by Vibeke Ann Muelle and Jesús Aníbal Flores. First, the Court will
refer to the President’s Order of July 27, 2018 (supra para. 10), in relation to the admissibility of the
corresponding statements and the relevance of transferring the expert opinions. The Court also
considers that the State’s observations call into question the evidentiary weight of the statements,

observations regarding the evidentiary value of the statements and expert opinions admitted, as
applicable, together with the entire body of evidence in the present case.

FACTS
C. Background
43. Oscar Muelle Flores is a civil engineer33 who worked for a mining company, the Empresa Minera
Especial Tintaya S.A. (hereinafter “Tintaya S.A.” or “Tintaya company”), from June 1, 1981, until
September 30, 1990.34 Tintaya S.A. was a State-owned enterprise until it was privatized in November
1994 (infra para. 57). During that time, Mr. Muelle held various different positions within the
company, the last one being the position of Assistant General Manager until his retirement.35
44. On May 15, 1990, the State-owned company issued Resolution No. AD-0884/90-R, according
to which Mr. Muelle Flores was included in the pension scheme under Decree Law No. 20530 “Rules
Governing Pensions and Benefits for Civil Servants in the Service of the State,”36 which acknowledged
that Mr. Muelle had provided services to the State for 35 years, 10 months and 27 days. 37
45. The decision to include Mr. Muelle Flores in the aforementioned pension scheme was based on
Board of Directors Decisions No. 155/88 of December 22, 1988 and No. 029/90 of February 8, 1990 38,
which authorized the government to include company employees in that pension scheme and
established the corresponding regulations for that purpose.39
The Court received the statements rendered by affidavit from the witnesses offered by the representatives, namely,
Vibeke Ann Muelle Jensen and Jesús Aníbal Delgado Flores, together with the expert opinions of Christian Courtis and César
Gonzáles Hunt, offered by the Commission and the State, respectively. The purpose of these statements are established in
the Order of the President of July 27, 2018 (supra para. 10). Available at: http://www.corteidh.or.cr/docs/asuntos/muelle_27_07_18.pdf
