Sometimes they instruct external solicitors even when they have their own in-house legal teams, shockingly, for mediations as well as tribunals.
Even if they are not representing the LAs, they are often around advising in the background. Interestingly, the Government isn't interested in addressing this massive power imbalance with the CFB.
I have received this advice on the DPA from a specialist legal team:
There is no blank cheque for sharing information, if that information is personal data. The law defines personal data very broadly, and includes expressions of opinions about the person, or indications of intentions in respect of them. If they are data that relate to your child, and your child can be identified from those data, there are limitations that will apply to how they can be processed which includes sharing them with other people.
For example, if you were to make a written request on your child's behalf, the LA (a data controller) would generally have to tell you whether it is sharing your child's personal data, and give a description of the data, why they are being processed, and with whom they are being shared. There are exceptions to this obligation for health or education-related data processed for court proceedings, or where carrying out the obligation would cause serious harm to any person which don’t appear relevant in this case. However, if a data controller has already complied with a request to that effect, it won’t be obliged to comply with a similar request until after a reasonable interval has passed.
Generally, a data controller can only share personal data in the first place when it can meet one of several conditions. Consent is one of those conditions, but there are others it might be able to rely on if consent hasn’t been given. For example, a data controller can share personal data for the purposes of a “legitimate interest”, as long as the sharing doesn’t unreasonably prejudice the legitimate interests or rights of the data subject. Also, the sharing still needs to be fair and in line with data protection principles: accurate, up-to-date, and not excessive. Whether something is a “legitimate interest” will depend on the particular reasons and facts behind each instance of sharing, but it will always need to be reasonable.
Details about your child's physical or mental health or condition are classed as sensitive personal data, however, and subject to stricter controls. Consent is far more commonly required to share those data: although there are some circumstances in which a data controller can share that data without consent, those are less easily applied. For example, if it was necessary in order to perform one of the functions given to the LA by law. If the LA couldn’t show that was the case, and sensitive personal data was shared without consent, this would be something to approach the ICO with
