removeRepetitions[L_] := Fold[If[#2==Last[#1],#1,Append[#1,#2]]&,{First[L]},Rest[L]] successfully removes dublicates in lists like {1,2,2,3,6}.
Is it an easy way to extend the functionality of this function such that it works with lists like
{{1,2,3},{44,56,78},{1,2,3},...} removing dublicate elements such that {1,2,3}?
