Key legal question
Whether refusing access to the doctor's letter violated the appellants' right to be heard and file inspection rights
Extracted holding
The refusal did not violate the right to be heard because the opposing public and private interests outweighed the parents' interest in full access at this stage.
Extracted reasoning
File inspection covers decisive pieces but can be restricted after case-by-case balancing. Here, protecting the possibility of a further criminal inquiry and the child's interest in discovering the truth justified temporary nondisclosure.
