If the victim is not the earning member of the family, the compensation cannot be reduced on that pretext.
So, in 1994, the legislature had fixed the income of a non-earning person at Rs 15,000/- per month and in case of a spouse, it would be one-third income of the spouse if he is an earning member, as per the Schedule II of the M V Act. The Schedule II has been removed by the 2019 amendment of the M V Act.
However, some High Courts started fixing higher notional income, such as Rs 25,000/, based on increasing living expenses for such persons having no income.
