Ajuda - Case

Question

     
CREATE PROCEDURE [dbo].[spGetItemsHeader]
(
	@Name varchar(50) = NULL,
	@Date datetime    = NULL,
	@Active smallint  = NULL
)
AS
BEGIN
  SELECT idItemHeader,
	     dsName,
	     dsUrl,
	     dtVigenciaIni,
	     dtVigenciaFim,
	     nuPrioridade,
	     dsType
  FROM   tbItemsHeader
  WHERE  (dsName = NULL OR dsName LIKE '%' + @Name + '%')
     AND (@Date BETWEEN dtVigenciaIni and dtVigenciaFim)
     AND (CASE @Active
         WHEN 0 THEN (GETDATE() NOT BETWEEN dtVigenciaIni AND dtVigenciaFim)
         WHEN 1  THEN (GETDATE() BETWEEN dtVigenciaIni AND dtVigenciaFim)
         END = @Active)
END

 

Pessoal, como ficaria o case acima corretamente dentro da clausula where?
