In a stepfamily who should do the disciplining?

It's always a good rule of thumb to have the biological parent provide the actual consequences or punishments. Otherwise, every kid feels the same thing — who put you in charge?

Please remember, you two fell in love, the child is just an innocent bystander here with enormous changes being forced on her. This doesn't mean that the stepparent can't report to the biological parent that the child did something wrong and deserves consequences.

It also mean the stepparents can tell the kid (if the biological parent isn't around) to stop some offensive behavior. But when it comes to grounding the kid or taking something away, that's the job of the biological parent.
