A bigamous marriage contracted before the commencement of the Hindu Marriage Act, 1955:

Section 11 of the Hindu Marriage Act declares void only marriages solemnized after the commencement of the Act that contravene section 5(i), so the Act does not retrospectively invalidate an earlier bigamous marriage that was valid under the law then applicable: such a marriage "remains valid". It does not become void or voidable because of the 1955 Act, although any earlier local prohibition must be assessed separately.
