We are informed that the State of Texas has adopted new apportionment legislation providing single-member districts to replace the multimember districts which are at issue before us in this case. That statute by its terms does not become effective until the 1976 elections, and intervening special elections to fill vacancies, if any, will be held in the districts involved as constituted on January 1, 1975. Rather than render an unnecessary judg *936 ment on the validity of the constitutional views expressed by the District Court in this case, which we do not undertake to do at this time, we vacate the judgment of the District Court and remand the case to that court for reconsideration in light of the recent Texas reapportionment legislation and for dismissal if the case is or becomes moot.

So ordered.
