           1 = 
                case when @P3 = '<All>' then 1
                         when t1.Year in (@P3) then 1 
                         else 0 end

Note that you may have to split the parameters into a temporary table.  There are plenty of ways to do that but not sure what @p2/@p3 actually represent right now.

 (@P2 = '<All>' or T1.Quarter in (@P2)) AND
 (@P3 = '<All>' or T1.Year in (@P3))
