Under the Evidence Act an admission is defined as a statement oral or written which suggests an inference to a fact in issue or a relevant fact made by one of the parties to the proceedings.
Admissions are classified into
1. Formal Admissions;
2. Informal Admissions;
Informal admissions are those admissions that are made before any proceedings are anticipated and this is covered at Section 17 to 24 of the Evidence Act.
Formal admissions are made in the context of specific proceedings and the effect of formal admissions is that they dispense with proof with regard to the be made. They will be made in answer to a notice to admit and they could also be made by Affidavit. The distinction between formal admissions is that formal admissions are made with respect to proceedings while informal are made with respect to anticipated proceedings.
In the area of criminal law, admissions will be under what is called confessions. Sections 25 –32 deal with confessions.
According to Section 24 admissions are not conclusive proof of the matters that they admit but they could operate as estoppels and many writers on S. 24 wonder why the legislators put that provision knowing that under Common Law Admissions if admitted are conclusive proof. But essentially we are saying even though they are not conclusive they amount to estoppel. The idea of estoppel in admission is to prevent a person to assert things that are at variance with things they had admitted before.
Section 61 deals with facts admitted in Civil Proceedings is to the effect that no fact need to be proved the main principle is that once you admit certain facts, you will not be required to prove those facts but unless the court may by discretion require those facts to be proved.
