Mediclaim policy renewal is mandatory on insurer

From a consumer advocacy website CERC:
  Mediclaim policies, considered a panacea, prove a headache when one goes for a claim or renewal. A recent judgement of the Gujarat High Court mitigates the grievances of the policy holders to a large extent by directing the insurance companies to renew Mediclaim policies on existing terms and conditions.
