Hi Folks,
Here is the remedy to prevent similar situation in future.
1 Strict rules for mentors ( no talk about personal lives of contestants by them)
2 one person one vote and votes should be audited by third party
3 in final rounds divide weightage 50% weight to public voting, 25% to mentors 25% to a well qualified judge
4 instead of just giving numbers we need to judge contestant in multiple discipline
a) quality of voice
b) range of voice
c) originality
Tell me your views.
