What is the term used when a party believes there has been an error made by the trial court judge and seeks a review from a higher court?

The term used when a party believes there has been an error made by the trial court judge and seeks a review from a higher court is "appeal." An appeal is a legal process through which one party requests a higher court to review the decision of a lower court. The appealing party, known as the appellant, argues that errors were made in the trial that affected the outcome of the case, and seeks to have the higher court overturn or modify the trial court's ruling.

In the context of the judicial system, the appeal process is fundamental as it upholds the principle of checks and balances, allowing for corrections in the judicial system and ensuring that the rights of the parties involved are respected. It's an essential mechanism for providing justice and maintaining the integrity of the legal process.

Other terms mentioned, like intervention, refers to a procedure by which a third party can enter into a lawsuit to protect their interests; reversal pertains to the outcome of an appeal when a higher court decides to overturn the lower court's decision and litigation is a broader term that encompasses the entire process of taking legal action, rather than specifically seeking a review of a lower court's decision.
