No it doesn't. Maybe it shows that they can afford better legal representation than you, but the law is the same for all - you can't falsely accuse someone of something illegal (dodging tax in this case). If I publicly and in writing accuse you of dodging tax by claiming medical expenses relief, you would have recourse to take me to court over it too. That you mayn't be able to afford to do so - or even have the inclination to do so - is irrelevant.
