Supreme Court dismissed cassation; expert institute opinion unnecessary when expert conclusions are consistent.

The Supreme Court dismissed the applicant's cassation appeal against a decision denying a permanent disability pension. The applicant argued that an expert institute opinion was required to resolve doubts about the nature of his health condition, but the lower courts had already established consistent expert findings regarding his partial inability to work. The court ruled that obtaining an institute opinion is only necessary when complex research is needed or when existing expert opinions contradict each other, neither of which applied here.
