B.C. Human Rights Tribunal has asked an anti-Smart Meters group to come back with an amended "class action" style complaint after ruling the group's submission as overly broad Tuesday.

Citizens for Safe Technology Society represents a number of individuals who claim doctors have advised them to stay away from the digital devices because of potential harms.

The tribunal will only hear cases of those "allegedly diagnosed" with electromagnetic hypersensitivity (EHS), which BC Hydro said isn't accepted as a disability in B.C., or elsewhere, according to the tribunal decision.

The society, meanwhile, describes EHS as an "environmental sensitivity resulting in an inability to be well while residing in a residence . in which a wireless smart meter has been installed."
