Please inform me, whether both of the above sentences are correct or not ? If correct, in which situation we could use each of the above sentences particularly.

As far as I know, it is best to use the simple past, i.e. sentence 1 when I know when the situation happened, like yesterday or this morning or so...also, it gives me the impression that he didn´t bring the documents and now it´s too late anyway , so there´s no need to bring them anymore.

As for the second sentence, I don´t specify when it happened , it´s not important to know when but what happened and ..he hasn´t brought the documents ( yet ) but there is a chance to do it so.
