Why To Lie About Degrees When Law Doesn't Ask For It?

The constitution permits any Indian citizen above 25 years of age to contest the Lok Sabha and 30 years to become eligible for Rajya Sabha, if he is not convicted of any offence and sentenced to an imprisonment for two years or more.

In other words, even if the member is illiterate and uses his thumb imprint to sign, he or she qualifies to become a parliamentarian.

If educational qualification is not a criterion to become a peoples' representative, why do parliamentarians lie about educational qualifications and produce fake degrees?
