Quick Summary

The playwright of Hum Hindustani said the film New Delhi copied his work. The Supreme Court held: ideas are free; expression is protected. Both works drew from a similar idea, but the film’s treatment, scenes, and details were different. So, there was no copyright infringement.

Issues

  • Is the film New Delhi an infringement of the play Hum Hindustani?
  • Did the producers/distributors/exhibitors of the film infringe the plaintiff’s copyright?

Rules

  • Idea–Expression Dichotomy: copyright protects original expression, not mere ideas, subjects, themes, plots, or facts.
  • Ordinary Observer Test: if an average viewer gets the clear impression of copying, infringement may be found.
  • Similarity of general idea is not enough; there must be substantial similarity in expression (scenes, sequence, incidents, dialogue).

Facts (Timeline)

view

1953: R.G. Anand writes the stage play Hum Hindustani after its success considers a film version.

1954: Director Mohan Sehgal shows interest by letter; they discuss the play in detail.

Later: No commitment follows; a film titled New Delhi releases. The playwright believes it follows his plot.

Suits & Appeals: Plaintiff seeks injunction and damages. Trial Court and High Court rule against him on facts; case reaches the Supreme Court.

Arguments

Appellant (Plaintiff)

  • The film New Delhi adopted the plot of Hum Hindustani.
  • Meetings and discussion show access; similarities show copying.
  • Sought injunction and damages for infringement.

Respondents (Producers & Ors.)

  • Only a broad idea is common; expression is different.
  • Scenes, sequence, characters, and treatment are original.
  • Ordinary viewer would not find a copy.

Judgment

No Infringement

The Supreme Court upheld the lower courts. It found only a negligible similarity at the level of idea. The contexts and execution were significantly different. Therefore, no breach of copyright.

  • Ideas, themes, and plots are free for all; protection lies in expression.
  • Use the ordinary observer test to judge overall impression.

Ratio Decidendi

Copyright protects original expression, not the underlying idea. Similarity in the general idea or theme is not enough; there must be substantial similarity in the form of expression such that an ordinary person would conclude one work is a copy of the other.

Why It Matters

  • Key Indian authority on idea–expression in creative works.
  • Guides film, theatre, and OTT disputes on “similar plot” claims.
  • Encourages originality in treatment, not monopoly over general ideas.

Key Takeaways

  • Ideas/themes are public; expression is private.
  • Ask: Would an ordinary person see a copy overall?
  • Access + similarity ≠ infringement unless expression overlaps.
  • Protect scripts through drafts, registrations, contracts.
  • Record differences in scenes, sequence, and details.

Mnemonic + 3-Step Hook

IDEA ≠ EXPRESSIONIdea is free, Details are guarded, Expression is key, Average viewer decides.

  1. Spot: Are we comparing ideas or expression?
  2. Scan: Look at scenes, sequence, incidents, dialogue.
  3. Say: Would an ordinary viewer think it’s a copy?

FAQs

No. Copyright does not protect ideas. It protects the unique way you express the idea.

Show access and substantial similarity in expression—scenes, sequence, and details—not just a shared theme.

Keep drafts and timestamps, register where possible, and share under written contracts or NDAs.
