A lawyer for the family of murdered former INLA leader Dominic McGlinchey has urged the Irish government to "radically improve" how it deals with legacy issues.
Originally from south Derry, ex-INLA 'chief of staff' Dominic McGlinchey was shot dead in Drogheda, Co Louth, on February 10 1994.
His wife Mary was gunned down while bathing her young children at their home in Dundalk, Co Louth, on January 31 1987.
The couple's son, also called Dominic, witnessed both murders, which remain unsolved.
The McGlinchey family has been involved in a process to uncover the circumstances of the murders.
Earlier this week relatives, including Dominic junior and his uncle, Sinn Féin councillor Sean McGlinchey, inspected an inquest file linked to Mr McGlinchey's death at a coroner's office in Co Louth for the first time.
The family is currently taking judicial review proceedings against the coroner for Co Louth.
Dundalk-based solicitor Ciarán Mulholland, of Mulholland Law, branded the state approach as "shocking".
"The Irish state must radically improve how it deals with legacy issues arising from the Troubles in a manner compatible with EU jurisprudence and in the spirit of the Good Friday Agreement," he said.
He said initial inquests into both murders "were systematically flawed and warrant fresh inquests".
The solicitor added that gardai have not responded to correspondence and urged commissioner Drew Harris to engage with relatives.
"Furthermore, it is only right and just that the Garda commissioner now engage with our client as the failures to respond to multiple correspondences is not only unsatisfactory but incredibly uncompassionate, adding insult to injury," he said.
The Irish government and gardai were contacted.
