Firstly, there are many other politicians whose affidavits have similar issues. Now the reasons for these issues are two-fold.Casual errors. Most affidavits are filled by support-staff/lawyers, and the candidate probably does a summary look at the details. An example is Commando Surinder Singh (AAP MLA from Delhi). His affidavit shows he graduated from University of Sikkim, whereas he actually graduated from a college that was in Sikkim. Even courts sometimes accept it as clerical errors.Deliberate errors. In such cases, politicians want to hide an uncomfortable fact, and they play with the words of law. For example, Modi’s case where he was technically married but never did gauna.The real problem is that unless the errors are glaring and obvious, EC would rarely reject the nomination on grounds of wrong affidavit. After that, courts take years to determine whether an affidavit was wrong or not.Unless the penalty for wrong affidavit is very high and the decision being swift, most politicians would play hanky-panky with affidavits.
