Admissibility
Definition
Whether a piece of evidence is permitted to be placed before the fact-finder at all. Admissibility is a threshold question, decided by the judge before trial or at the start of the relevant evidence. It is distinct from weight, which is how much the fact-finder values the evidence once it is in.

Common questions
What is the difference between admissibility and relevance in court?+
Admissibility is whether the court will accept and consider evidence at all. Relevance is whether evidence connects to the facts in the case. Evidence can be relevant but still inadmissible, or vice versa. The judge decides admissibility before trial as a threshold question.
Why would evidence be excluded from trial?+
Evidence can be excluded for many reasons. One of the most common is a broken chain of custody, which shows the evidence was not properly handled or documented. Other grounds for exclusion exist, but admissibility rules vary by jurisdiction.
How is admissibility different from weight?+
Admissibility decides whether evidence gets in front of the judge or jury at all. Weight is how much the fact-finder values the evidence once it is admitted. A judge decides admissibility. The fact-finder (jury or judge) decides weight.
