Cassation court dismisses appeal regarding admissibility of evidence in immigration detention proceedings due to procedural defects.

The Court of Cassation dismissed the appeal lodged by the applicant against the lower court's decision on the admissibility of evidence. The applicant argued that certain documents presented during the immigration detention review were improperly obtained and should have been excluded. The court ruled that the procedural irregularities did not justify the exclusion of the evidence under the relevant administrative law principles.
