   このような問題もんだいの前例ぜんれいはない。↗

   There is no precedent for such a case.

• Synonym先例せんれいFormalLeans formal, but also used in spoken discussion (「先例に倣う」). Nearly synonymous with 「前例」; the two are largely interchangeable.
• Antonym後例WrittenA later case; the opposite of 「前例」. Rare and written in flavor; not normally used on its own in everyday speech.
• Antonym無例WrittenMeans having no precedent; the opposite of 「前例」. Rare—normally say 「前例がない」 instead.

Use 「前例」 for a similar past case (「前例のない事態」「前例に従う」); 「先例」 also works, especially in writing. 「後例」 and 「無例」 are rare written opposites—to say there is no precedent, use 「前例がない」.
