Explain 'Protection against arrest and detention in certain cases'.
Protection against arrest and detention in certain cases refers to the safeguards provided by the constitution to ensure that a person's right to life and personal liberty is not violated through arbitrary arrest or detention. This protection includes the following rights:

1. A person cannot be arrested without a warrant, unless there are reasonable grounds for believing that they have committed a non-bailable offense.
2. A person who has been arrested must be informed of the reasons for their arrest and given the opportunity to consult with a lawyer before being questioned.
3. If a person is detained in custody pending trial, they have the right to be brought before a court within 24 hours of their arrest, and to be released on bail if the court decides that it is appropriate to do so.
4. A person who has been arrested or detained cannot be subjected to any form of torture, cruelty, or inhuman treatment while in custody.
5. A person who has been arrested or detained can apply to a court for a writ of habeas corpus, which requires the authorities to bring the person before the court and explain the reasons for their arrest or detention.

These protections are intended to ensure that the government cannot arbitrarily deprive individuals of their liberty without due process of law.
