A more thorough explanation:

Denunciation means to publicly condemn or accuse someone or something. It can also refer to a declaration of a threatened action or an application for a grant to work a mine that is either newly discovered or forfeited.

• The denunciation of the corrupt politician by the opposition party led to his resignation.
• The denunciation of the proposed law by human rights groups caused it to be revised.
• The denunciation of war by the president was met with both support and criticism.

These examples illustrate how denunciation can be used to publicly condemn or accuse someone or something, as well as how it can be used to declare a threatened action.
