Facts
The insured person, born in 1967, first registered with the Invalidity Insurance in August 2011 due to a mental illness. The IV-Stelle of the Canton of Zurich denied a pension entitlement by decision of 24 September 2012. In early May 2014, the insured person again applied for invalidity benefits.
From February 2015, the IV-Stelle carried out occupational rehabilitation measures and paid daily allowances. On 3 August 2016, the insured person completed the work training. Based on a multidisciplinary expert report by medexperts AG of 23 February 2017 (including a psychiatric partial report and supplement of 19 September 2017), the IV-Stelle rejected the benefit application by decision of 11 December 2017 (degree of disability 20%).
The Social Insurance Court of the Canton of Zurich partially upheld the appeal by decision of 23 August 2019. It granted the insured person a three-quarter pension from January to July 2015 and a half pension from August 2015 to November 2016.
The IV-Stelle files an appeal in public law matters and requests the annulment of the lower court's decision and the confirmation of the decision of 11 December 2017; it also requests suspensive effect. The insured person substantially requests dismissal of the appeal. The Federal Social Insurance Office waived submission of a response.
Subject matter of dispute: Whether the lower court violated federal law by granting the insured person a three-quarter invalidity pension for January to July 2015 and a half invalidity pension for August 2015 to November 2016.
Considerations
Scope of review: The Federal Supreme Court applies the law ex officio (Art. 106 para. 2 FSCA), but, taking into account the duty to raise and substantiate complaints (Art. 42 paras. 1 and 2 FSCA), examines only the arguments raised, unless other defects are manifestly evident. The lower court's findings of fact are in principle binding, unless they are manifestly incorrect or based on a violation of law (Art. 105 FSCA). The multidisciplinary expert report by medexperts AG (including the psychiatric partial report) is undisputedly decisive as the evidentiary basis.
Lower court's considerations: The lower court assumed a 70% work capacity in the previous occupation from 1 September 2016 (degree of disability 30%, not entitling to a pension). Based on the retrospective psychiatric assessment, it set the earliest possible pension commencement at January 2015 and, taking Art. 88a para. 1 IVO into account, granted a three-quarter pension or a half pension. Participation in measures under Art. 14a InvIA does not preclude the pension entitlement under Art. 22 para. 5ter InvIA.
Principle 'rehabilitation before pension': Pension benefits are only to be paid once no reasonable rehabilitation measures remain under consideration (Art. 28 para. 1 let. a InvIA). A pension entitlement arises only after the end of the measures, even in the case of partial success or failure. Before that, a pension may only be granted if the insured person is not yet capable of rehabilitation or not capable at all (BGE 121 V 190 consid. 4c-e).
Capacity for rehabilitation during receipt of daily allowances: The insured person received daily allowances for integration measures under Art. 14a InvIA from February 2015 to August 2016. After expiry of the waiting year (Art. 28 para. 1 let. b and c InvIA), according to the retrospective assessment, there was a 40% work capacity from January 2015 and a 50% work capacity from May 2015 to August 2016. The insured person was therefore, from a medical standpoint, capable of rehabilitation, so no pension entitlement exists for this period (Art. 29 para. 2 InvIA).
Provision not applicable: Art. 22 para. 5ter InvIA provides that the insurer pays a daily allowance in addition…
