How did the Supreme Court in the Romesh Thappar vs. State of Madras case differentiate between 'Public Order' and 'Security of the State', leading to the First Amendment?

Explanation

In Romesh Thappar (1950), the Supreme Court noted that Article 19(2) originally contained Security of the State but omitted Public Order. The court held that the state could not ban a journal merely for minor law and order issues. This prompted Parliament to insert Public Order as a valid restriction in the First Constitutional Amendment Act, 1951.
