The following are redresses available at the courts for aggrieved people except _________

The redresses mentioned in the question are legal remedies that can be sought at a court of law to address grievances or injustices. Injunction, mandamus, and certiorari are all valid redresses that can be sought at a court of law to address various grievances. Injunction is a court order that prohibits someone from doing something or requires them to do something. Mandamus is a court order that compels someone to do something that they are legally obligated to do. Certiorari is a court order that requires a lower court to deliver its record in a particular case so that the higher court can review the case. Prorogation, on the other hand, is not a legal remedy available at a court of law for aggrieved people. Prorogation refers to the suspension of a legislative session, which is a political decision and not a legal remedy. Therefore, the correct answer to the question is prorogation.
