Key legal question
Whether the temporal connection between the earlier incapacity of work and the later invalidity was interrupted by the insured's work capacity from August 2003 to January 2004.
Extracted holding
The work capacity during that period was not shown to be sufficiently durable to break the temporal connection.
Extracted reasoning
Given the fluctuating psychiatric condition, the short and unclear period of apparent improvement, and the rapid relapse after resuming full-time work, the lower court could reasonably find a continuing temporal connection on the balance of probabilities.
