The decision to release the man who brutally killed a young woman in a flat in Cardiff will not be reviewed, the Ministry of Justice has said.
Jeffrey Gafoor, 59, is set to leave prison on parole after attempts to change the decision to release him failed.
Gafoor stabbed Lynette White more than 50 times on Valentine's Day in the city's docklands in 1988.
The Ministry of Justice said: "After thorough consideration, we have unfortunately found no legal basis for the Lord Chancellor to ask the independent Parole Board to reconsider its decision to release Jeffrey Gafoor."
