Praveen Halappanavar, whose wife Savita died as a result of a miscarriage in an Irish hospital last year, maintains the couple asked repeatedly for an abortion, but were told Ireland "is a Catholic country."
His solicitor said he was not satisfied with the results of a report by Ireland's Health Service Executive (HSE).
Mr Halappanavar, a 34-year-old engineer at Boston Scientific in Galway, has so far refused to co-operate with separate investigations by Ireland's health watchdog and the HSE.
He previously said his late wife is giving him the strength to "fight for the truth" and that he will make a decision on whether to take the Irish Government to the European courts in pursuit of a public inquiry after the inquest.
