Three key questions that the inquiry must answer
1. Does Mr Callely's sworn evidence that he has been living in west Cork for "60pc plus" of the time since 2007 stack up?
He has admitted himself that he has been very visible in Clontarf (the location of his Dublin home), walking his dog on the promenade, working out in the gym and shopping locally. And his website proclaimed him to be living in Dublin. But Mr Callely insisted yesterday that his house in west Cork was his principal residence.
2. Why did Mr Callely make no claims from his former holiday home in west Cork for the last four months of 2008 and 2009?
Mr Callely said in his letter to the Seanad authorities that he felt "this best reflects my particular situation". But he denied it was because he was trying to "re-balance" things out or "pay back" extra money he had taken from the system.
3. Was Mr Callely himself recognising there was a problem with his travel expense claims when he contacted the authorities to enquire about changing his normal residence in west Cork in May last year?
He said he was simply making an inquiry, but some committee members did not seem convinced by this explanation.
