Renewed calls have been made for a Hillsborough Law to ensure fairer treatment for bereaved families.
Liverpool City Region Mayor Steve Rotheram and Greater Manchester Mayor Andy Burnham said the government needed to "level the scales of justice".
It comes after a TV drama telling the story of Anne Williams, whose son died in the disaster, aired this week.
The government said it would engage with bereaved families and "carefully consider the points of learning".
Ninety-seven Liverpool fans died as a result of the crush at the FA Cup semi-final match at Sheffield Wednesday's ground on 15 April 1989.
