How to say "repeal" in Japanese

• 撤廃てっぱいCommon
  noun, suru verb, transitive verbRepeal as the outright abolition of a law, treaty, or system — doing away with the whole thing rather than taking back a statement or decision; the typical settings are legal and political.
  彼女かのじょは女性じょせい差別さべつ撤廃てっぱいを主張しゅちょうした。↗

  She advocated equal rights for women.
• 廃止はいしJLPT N1approx.Common
  noun, suru verb, transitive verbThe general word for abolishing or discontinuing a law, system, institution, or practice so that it ceases to exist; for plain 'repeal a law' this is usually the word you want.
  アメリカは奴隷制どれいせいを廃止はいしした。↗

  America did away with slavery.
• 撤退てったいCommon
  noun, suru verb, intransitive verbReally 'withdrawal' or 'retreat' — an army pulling back or a company quitting a market; its link to 'repeal' is thin, so it is seldom the word you want for repealing a law.
  ソ連それん軍ぐんはアフガニスタンからの撤退てったいを開始かいしした。↗

  The Soviet troops started to withdraw from Afghanistan.
• 撤回てっかいCommon
  suru verb, transitive verb, no-adjectiveThe taking back of something one has said, proposed, or decided — retracting a statement, withdrawing an opinion or an order; for 'repeal' it fits revoking a decision, not abolishing a law.
  自民党じみんとうは増税ぞうぜいの法ほう案あんを提出ていしゅつしたが、猛烈もうれつな反対はんたいにあって撤回てっかいした。↗

  The LDP brought out a bill to raise taxes, but they met with such violent opposition that they backed down.
• 廃棄はいきJLPT N1approx.Common
  noun, suru verb, transitive verbChiefly the discarding or disposal of physical things; its annulment and abrogation senses are legal ones, so it is seldom the word you want for repealing a law.

For repealing or abolishing a law or system, 廃止 is the plain choice and 撤廃 presents it as outright abolition; 撤回 retracts statements or decisions; 撤退 and 廃棄 are really withdrawal and disposal, only marginal for 'repeal'.
