The short answer is yes, but it wouldn't go far enough. You would also have to clarify the use to which defence counsel proposed to put the record in order to trigger the application. The first step is clarifying what you mean by a “record”. Narrowing it to the complainant is one step, but then it is also necessary to clarify what you mean when you say that defence counsel intending to use this record has to bring an application.
You can narrow it further at that stage by saying that it's only when defence counsel actually wants to put the private record into evidence that these applications are triggered. This would remove a lot of ambiguity about other ways in which we sometimes rely on material in our possession to prepare our defences.
