Praveen plans to drag the case to the European Court of Human Rights (ECHR). Last week's inquest into Savita's report did not yield any answers.
"There are still some questions that need answered. I haven't got my answers yet. I owe it to Savita and I owe it to Savita's parents to get all the answers and all the truth," he said.
The seven-day inquest which concluded at Galway Courthouse last Friday with a verdict of "medical misadventure".
The limited boundaries of an inquest had to be explained to Savita's parents, Andaneppa and Akhamahadevi Yalagi, who are based in Karnataka though they were given updates by Praveen's legal team from the inquest twice every day.
Savita was 17 weeks pregnant when admitted to University Hospital Galway on October 21 last year. She died a week later from blood poisoning after doctors refused to terminate her pregnancy, telling her that the foetal heartbeat was still present and Ireland is a Catholic country.
