							| I think it is wrong because�"have finished"�is the past infinitive, which is not necessary in this case since the past is already expressed in "didn �t have to".� |  22 Nov 2010

							| This sentence is completely correct: 
 Anne didn �t have to finish the project on her own.

							| The second sentence is correct, at least grammatically... 
 She didn �t have to have finished - is a perfect modal like "She shouldn�t have finished the project on her own."
 
 The second sentence is using "have to" in the past modal tense. It looks rather strange but it is, I believe, correct.
 
 Cheers,

							| Ann didn�t have to finish yhe project means that it wasn�t nesessary to do it and she didn�t. 
 
 Ann needn�t have finished her project means that it wasn�t necessary but she finished it.
 
 I think Ann didn�t have to have finished her project is incorrect because didn�t have to
 
 can�t   be followed by a perfect infinitive
