Praveen Halappanavar is calling time on the government as today is the deadline he set for the establishment of a public enquiry into the death of his wife.

Savita died from blood poisoning arising out of a miscarriage a month ago in Galway.

This has been marked by her friends and family this week with a vigil held at NUI Galway yesterday.

Her widower says he does not trust the Health Information and Quality Authority (HIQA) and Health Service Executive (HSE) inquiries already established and has threatened to take his case to the European Court of Human Rights.

Europe would take the case under the European Convention for Human Rights if there is a risk the existing investigations will not uncover how Savita died and whether the State bears some responsibility.

Separate investigations

HIQA announced earlier this month say they would investigate the care and treatment provided to her following a request from the HSE who is conducting a separate investigation.

The board of HIQA  say they will investigate the safety, quality and standards of services provided by the HSE at University Hospital Galway (UHG) to critically ill patients, including critically ill pregnant women as was reflected in the care and treatment provided to Mrs. Halappanavar.

The investigation will assess whether the services provided complied with the National Standards for Safer Better Healthcare and national and international evidence of what is known to achieve best outcomes.

The Authority says it has requested and received information from University Hospital Galway and the HSE to establish the facts about the case.

Conor O'Mahoney is a lecturer in constitutional law at University College Cork (UCC).

He says the government could use the Commissions of Enquiry legislation which is the same legislation used to establish the child abuse inquiries to set up a public enquiry.

He told Breakfast here on Newstalk it would be quicker and cheaper than other options but still public.
