Like all other reports it will remain on some shelf and gather dust. When a govt is to be seen as taking action, it goes and asks some commission to investigate and file a report. The report as usual will take some months to several years. In the meantime victims are happy that some investigation is going on, govts are happy as they are seen to be taking action and the perpetrators are happy that no action would be taken against them. After all in Indian polity no political party is flawless & will never take action against any other party or influential individual because they never know who would be in power next? So its not surprising that the real perpetrators of the anti-sikh riots, babri riots, godhra, terrorist attacks are all scot free.
