Sefton Central Labour MP Bill Esterson said the governmnt is obliged to hold a debate and vote in parliament to force a new inquest into the death of Kevin Williams.
The MP has written in the Mirror calling for the government to debate Kevin's death at Hillsborough 23 years ago.
Fifteen-year-old Kevin is one of the 96 people who died at the 1988 Hillsborough disaster and his mum Anne gained 115,000 signatures on a petition on the government website calling for a debate in parliament.
The original inquest decided that all the victims were dead by 3.15pm on the day of the disaster, but witnesses have told Anne that Kevin was very much alive until at least 4pm.
Anne and many others who lost relatives and friends at Hillsborough have argued that the 3.15pm cut off was a convenient excuse to cover up mistakes made by the authorities on the day, notably the decision to prevent ambulances from going onto the pitch to give medical care.
More than 100,000 people signed that petition and a number of MPs asked for a debate to be organised by the Back Bench Business Committee.
Yesterday, Bill and his fellow Labour MPs called for time in the House of Commons schedule to hold a vote to force a new inquest into Kevin's death.
Tthe campaign missed out on a slot for a House of Commons debate because of a "lack of time".
