How to say "dissent" in Japanese

• 反対はんたいJLPT N4approx.Common
  suru verb, intransitive verb, no-adjective, na-adjectiveThe general word for opposition: being against a plan, proposal, or policy rather than voicing dissent. Its range runs from simple disagreement to resistance or hostility, so it is often broader than 'dissent' proper.

  I objected to paying the bill.
