Types of evidence that could be inadmissible

The basis of all criminal cases is evidence. Law enforcement need evidence before they can charge someone. The prosecution needs strong evidence to bring a case to trial. Defense strategies largely revolve around poking holes in evidence and creating reasonable doubt. 

Sometimes, evidence may be completely inadmissible. This means that it cannot be used against the accused. When does evidence become inadmissible? 

Lack of probative value 

Strong evidence has to have probative value. This means that it really adds something significant to the case in hand. For instance, a witness statement saying that they saw the accused at the time of the incident has high probative value. On the other hand, if a witness says that the accused offended them 20 years ago, this lacks probative value as it is not relevant to the case. 

When evidence has more prejudicial value than probative value, it is often ruled inadmissible.

Improperly obtained evidence 

Police officers have a host of powers to investigate crimes and bring people to justice. However, there are checks and balances. All individuals have constitutional rights that protect them from improperly obtained evidence. For example, searches should not be carried out in violation of an individual’s Fourth Amendment rights. The Fourth Amendment of the U.S. constitution protects people from unlawful searches and seizures. So, if evidence from a search was obtained without probable cause or a valid search warrant, it could be deemed inadmissible. 

Accusations and charges do not amount to guilt. You have a right to challenge the evidence against you. Seeking as much legal information as possible can help you with your defense strategies.
