Key legal question
Whether arrears for child disability pensions could be paid back to July 2010 despite the March 10, 2016 request
Extracted holding
No. The extinction period of five years meant only prestations due from March 2011 onward could be paid.
Extracted reasoning
A sufficiently clear written request on March 10, 2016 fixed the reference date. Under Art. 24 para. 1 LPGA, arrears older than five years were time-barred, even if the administration may earlier have failed in its duty to investigate.
