Key legal question
Whether the pension could be revoked by reconsideration because the 2004 communication was manifestly erroneous.
Extracted holding
The 2004 communication was undeniably wrong and the error was significant enough to justify reconsideration and revocation of the full pension from 1 June 2012.
Extracted reasoning
The expert evidence showed a marked improvement in health and full work capacity since 2004. The contrary medical reports lacked probative value and did not seriously undermine the decisive expert opinions.
