Or Mahesh is convinced of Sharad's guilt and he decides to find it out using a convoluted way:
1.) He presents a facade of fighting Sharad's case, while at the same time helping in the preservation of the 'Bajaj Khandaan Ki Izzat (his real goal)'
2.) He presents a weak defence and/or deliberately goofs up and gives clues to Manish Paliwal during the court sessions, that will eventually trap Sharad ?
What say you folks ?
