Section 300 of CrPC : Section 300: Person once convicted or acquitted not to be tried for same offence.

Explanation using Example

Example 1:

Ravi is accused of stealing a mobile phone from his colleague's desk at work. He is tried in a competent court and acquitted of the charge of theft. Later, new evidence surfaces suggesting that Ravi might have committed a criminal breach of trust by misusing his position at work to access the colleague's desk. However, since Ravi was already acquitted of theft based on the same facts, he cannot be tried again for theft or criminal breach of trust as per Section 300(1) of the Code of Criminal Procedure, 1973.

Example 2:

Sita is tried and convicted for causing grievous hurt to her neighbor during a heated argument. A few weeks after the conviction, the neighbor succumbs to the injuries and dies. In this scenario, Sita can be tried again for culpable homicide because the consequence of the neighbor's death was not known at the time of her initial conviction for grievous hurt, as per Section 300(3) of the Code of Criminal Procedure, 1973.
