The definition of the offence of giving false evidence thus applies to the affidavits. The offence may also fall within Section 192 which, inter alia, lays down that a person is said to fabricate false evidence if he makes a document containing a false statement intending that such false statement may appear in evidence in a judicial proceeding and so appearing in evidence may cause any person who, in such proceedings is to form an opinion upon the evidence to entertain an erroneous opinion touching any point material to the result of such proceedings. Therefore, where declarations in affidavits which were tendered in the Court to be taken into consideration, the authors of the affidavit clearly intended the statement to appear in evidence in a judicial proceedings and so appearing, to cause the Court to entertain an erroneous opinion regarding the compromise, therefore, the offence would fall within Section 191, 192 which is punishable under Section 193 IPC,
