Dear ....

I write to you to rescind my signature on .... (title of the document) dated ..... .

I just came to realize that I might not be the right authority to sign this document (or an extraordinary event beyond my control had just taken place prior to me signing and I was not aware.).

Please discard this (title of the document) document immediately and cease any circulation of it. Thank you for your cooperation.

Best,
