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

The Supreme Court dismissed the appeal against a lower court's decision to exclude evidence in an immigration detention case. The appellant argued that certain documents were relevant to proving the legality of the detention, while the opposing party contended they were obtained improperly. The court ruled that the evidence failed to meet the strict admissibility requirements for immigration proceedings, resulting in the exclusion of the contested materials.
