Whose correct?

Hi Boys and Girls,

One player jaws the black which is the last ball on the table-ball stays on the table next to the pocket, however the white goes in off. This then puts both players on an equal score.

Player two places the white ball in the D to take his shot, however player that went in off states that the black ball has to be respotted.

Could somebody please clarify the rules here please?

Thanks
