What a set of rules can achieve and what it cannot
A set of usage rules does not change what an AI tool can do. It changes who uses it for what, which information goes into it, and who bears the consequences.
1.1 Three effects
It makes visible what is happening anyway. The German data protection supervisory authorities describe the starting position unusually directly: without clear rules there is a risk that employees will use AI applications “on their own initiative and without control”, and it must be assumed that this is “currently the reality in many companies and public bodies”. Rules that name the tools provided by the company and open up reporting channels bring that use out of the invisible.

The document is in German; the quotations are the publisher’s translation. It sets out recommendations and is administrative guidance, not statutory text; it comes from a German body and interprets the General Data Protection Regulation, which applies throughout the Union.It moves decisions to where they belong. Without rules, each member of staff decides case by case whether a customer’s address may go into an external system. With rules, the company decides that — once, in advance, and the same way for everyone. The Austrian Economic Chamber puts the same thought in terms of tool selection: it is for company management alone to decide whether an application is permissible.

A recommendation by a representative body, not a legal source.It can itself be a protective measure to which legal consequences attach. Under Union law, information is a trade secret only if, among other things, “it has been subject to reasonable steps under the circumstances, by the person lawfully in control of the information, to keep it secret”. Protection therefore depends on an act of the holder, not on the value of the information alone.

No court decision was found that expressly brings a set of AI usage rules under that point, or that treats their absence as causing the loss of trade secret protection. The connection therefore remains a question each company must answer for itself, and not an established legal consequence (Section 13).
1.2 Four expectations it does not meet
It creates no freedom from liability. Who is liable follows from the applicable law and not from whether a document exists. The Economic Chamber puts it the other way round: clear rules are a means of reducing the liability risk — not of excluding it.

A rule referring to “approved tools” is worthless as long as nobody has decided which those are and by what measure. Section 5 deals with that decision.
It has no effect if nobody knows it. The supervisory authority places two requirements side by side: instructions should be issued and documented. A filed document meets only the second. Section 9 deals with bringing rules into force.
It answers no legal question. Internal rules may restate, summarise or tighten the law in force. They cannot change it — and where a legal question is open, internal wording does not close it.
Rules that promise more than the company delivers are evidence against it in a dispute. Anyone who undertakes that every entry will be checked, and has no logging, has not merely gained nothing but lost something. Section 7.13 deals with what, for that reason, does not belong in a set of rules.
1.3 What this handbook means by “rules”
What is meant is a written, dated set of provisions, made known to the workforce, stating whether, on what conditions and for what purposes which AI tools may be used at work. Whether they are called an instruction, a directive, a guideline or a works agreement is a question of national law and of company practice; the supervisory authority names the service or operating instruction and the service or works agreement side by side, without preferring either.
