Questão jurídica principal
Whether the claimant could obtain disability pension backpayment from the age of 18 rather than only from 1 March 2002.
Decisão extraída
No. Earlier backpayment was barred because the claimant learned the pension-triggering facts no later than summer 2001, yet he registered only on 3 March 2003.
Fundamentação extraída
Under Art. 48(2) second sentence IVG, retroactive benefits beyond twelve months before registration are payable only if the insured person could not know the relevant facts and registers within twelve months after learning them. The psychiatric treatment starting in 1995 and the internship in 2000/2001 showed earlier knowledge; the 2003 application was too late.
