Has Sushant Singh Rajput's film on Jaswant Singh Rathore aka 'Rifleman' been postponed?

Earlier this year Bollywood heartthrob Sushant Singh Rajput had announced about his upcoming film 'Rifleman' which will be based on the life of Jaswant Singh Rathore, who fought the battle of Nuranang in 1962.
According to reports, the film has landed in a legal problem due to rights to the biopic and the matter is currently being resolved in the court. The report even suggested that this issue has risen after the family of Rathore had a conflict with the makers of the film.
The report further suggested that the rights of the film were bought from a family member by Abundatia Entertainment and they had gone ahead and announced about the film with Sushant in the leading role but on the other hand, another member of the family had already sold the right to some other team, who are currently ready with their project with the title '72 hours'.
The trailer of '72 hours' had been released by the makers of the film last year in December but the project has been delayed due to this issue. While the makers of 'Rifleman' have denied these reports and said that their project is currently on track and is making progress.
