Questão jurídica principal
Whether the claimant's work capacity was sufficiently established and whether a medical expert report was still required.
Decisão extraída
The medical file and BEFAS report were sufficient; light, alternating work in a seated position for six hours daily with a 50% overall performance after adaptation was established.
Fundamentação extraída
The BEFAS report contained detailed medical assessment and could be used to question earlier non-medical findings; even the treating doctor supported light back-friendly work, so further evidence would not change the result.
