It prevented monarchs from having opponents arrested.
Explanation:
The Habeas Corpus Act of 1679 was an act that ensured that no one could be imprisoned unlawfully. This way, the Monarchy, which was used to arrest opponents and people who criticized it could not do it anymore.
This was one of the ways the Parliament limited the Monarch’s power, from now on the King could not suspend the parliament laws, could not raise taxes without consent, and other measures.
