I would like to know if there is legal precedent protecting the freedom of speech in distributing an open letter or something similar.
A friend owns a unit in a condominium, and since day one she has been subjected to random fines and hostility from certain neighbors. The condominium is managed by a private company, and the manager finds every opportunity and every excuse to slap fines on her, for all kinds of random things that she didn't do. She tried and fought back by filing complaints with fair housing organizations, but it has had little effect. The management company retracted some fines but still shows express hate and hostility toward her and fines her whenever they can.
My friend has requested a meeting with the HOA board many times in email to the manager, which have all been ignored or denied. Then an extremely discriminatory and hateful thing against her happened. With her access to the board blocked, she had no choice but to write an open letter to other residents, asking for their help, and leave the letters at their doors. A few weeks later the management company found out and slapped her with several other fines, claiming her act of distributing an open letter constituted a violation. (Funny thing is the section they cited in the Condominium Bylaw in regard to the violation doesn't even exist.)
Are open letters protected under the First Amendment to the U.S. Constitution? Are there other specific clauses on the federal and/or state level that are relevant in this case?
