Mahabharat
यॊ हि परश्नं न विब्रूयाद धर्मदर्षी सभां गतः अनृते या फलावाप्तिस तस्याः सॊ ऽरधं समश्नुते ॥ २-६१-५६ ॥
'You should also respond according to your judgment. One who, understanding the principles of morality and being present in the assembly, fails to answer a question, incurs half the demerit of a falsehood.' ॥ 2-61-56 ॥
