Sphere said the advocacy group NS4SED has sent threatening e-mails to its partners and tenants, and has attempted to interfere with its business.
Sphere did not reply to attempts made by The Spotlight to obtain copies of those e-mails.
Sphere also stated in the letter that respecting the citizens' desired interpretation of the comprehensive plan and still improving the tax base is a complex issue, but some have approached the subject in an "unprofessional" manner.
"Both of these goals are extremely important, serious and complex. The ultimate resolution of these complex issues should not be influenced, determined or clouded by unprofessional conduct, mob-mentality or intimidating tactics; rather it must result from a professional, selfless and fair process that makes all the citizens of New Scotland proud, not just the loudest ones," the letter stated.
Kormos' attorney, Peter Lauricella, said Kormos has acted only behalf of the town.
"She wants to get back to work on the CZAC process as soon as possible," he said.
He said he understands that there may be some discussion next week related to the matter.
Lauricella said he would not recommend any counter-action if the town drops the matter, although he has not spoken with Kormos specifically regarding the possibility. ""
