I haven’t seen the letter but from what I gather the gist of it is that since Belle Plaine, MN approved the monument instead of closing down the limited public forum for which it was intended, that the construction of the monument was commissioned in good faith with the expectation of approved placement. By waiting until after the monument’s construction, the town might well be liable for the expense if the approval constitutes a contract between the town and TST. (note: not a lawyer, I could be wrong). This is apparently called “promissory estoppel”.
