Loss under Section 94(7) & Sec 94(8)

Had a query... I understood that Section 94(8) and Sec 94(8) was earlier inserted when dividend on shares / Mutual funds was nil. Since dividends are now taxable, I think the relevant portion that disallows loss if sale within 3 months of dividend is probably no longer applicable. Am I right? If correct, how would someone raise this with the proper authorities ?
