That's not how you disclose potential litigation expenses to shareholders. You do not have to disclose the explicit details of the potential lawsuit to your shareholders, merely an estimated impact it may have, based on what the settlement would be and the likelihood of them losing/settling. The fact that the Niji lawyers are unable to share the doc with talents to verify the veracity of the document to properly assess the potential litigation expenses is a result of their own signing of the confidentiality agreement.
Again, that's not how any of this works. The confidentiality agreement was to not share the contents of the document. There was likely zero lawsuit being sent to Niji at this point and their lawyers would have no necessity to draft a response to it. What they stated was that Selen stated she was possibly looking into legal action against the talents themselves. If Selen did follow through and took legal action against the talents, the talents would see the document at that point when legal action is taken against them. Because Niji shared the document with the talents, they have now broken their confidentiality agreement and provided a case against themselves.
Let me rephrase this in a simple way for you to understand:
1) Doki shows Niji the doc and tells them to fuck off or she'll release it and that she's considering going after the talents
2) The confidentiality agreement prohibited Niji from sharing the document with anyone outside their legal team, likely to ensure that Doki wouldn't air it out to the public
3) For Niji's legal team, the fight is effectively over for them and resolved. However Doki may take legal action against the talents if she desired.
4) Niji is prohibited from sharing any details of the doc with the talents, which they do anyways
5) Niji is now open to legal action while their talents can still have legal action taken against them and Selen may release the doc to the public
