Questione giuridica chiave
Whether the insured had an invalidating mental impairment entitling him to AI benefits
Decisione estratta
The court held that the insured had not shown an invalidating psychiatric impairment; the file supported primary polytoxicomania, not a legally relevant psychical disorder.
Motivazione estratta
The Federal Court accepted the cantonal court's preference for the expert report because it was more detailed and convincing than the contrary medical opinions; the criticism merely opposed another appreciation of evidence.
