Hemant Patil's submissions, filed by his lawyer R N Kachave, cited several high court and Supreme Court judgements.
The poster, which created a controversy when it was released a few weeks ago, shows the actor standing in a semi-nude position on the railway tracks.
Civil judge M S Sharma posted the matter for further arguments next week.

The poster had been duly approved by the Film Publicity Screening Committee, a government body, they said.
