enacted a statute allowing for the use of an unsworn declaration under penalty of perjury in lieu of an affidavit in
federal courts.
In other words, the declarant's signature together with a statement that they were making the unsworn declaration under penalty of perjury were deemed as a matter of law to be sufficiently solemn to remind the declarant of their duty to speak the truth, the whole truth, and nothing but the truth (meaning notarization was no longer required).
As of 2006, about 20 states also had similar statutes allowing the use of unsworn declarations in their
state courts.
Unless a witness is testifying as an
expert witness
An expert witness, particularly in common law countries such as the United Kingdom, Australia, and the United States, is a person whose opinion by virtue of education, training, certification, skills or experience, is accepted by the judge as ...
, testimony in the form of opinions or inferences is generally limited to those opinions or inferences that are rationally based on the perceptions of the witness and are helpful to a clear understanding of the witness' testimony.
Legitimate expert witnesses with a genuine understanding of legal process and the inherent dangers of false or misleading testimony refrain from making statements of fact. They also recognize that they are in fact not witnesses to an alleged crime or other event in any way, shape or form. Their expertise is in the examination of evidence or relevant facts in the case. They should make no firm judgement or claim or accusation about any aspect of the case outside their narrow range of expertise. They also should not allege any fact they can not immediately and credibly prove scientifically.
For example, a hair sample from a crime scene entered as evidence by the prosecution should be described by an expert witness as "consistent with" a sample collected from the defendant, rather than being described as a "match". A wide range of factors make it physically impossible to prove for certain that two hair or tissue samples came from a common source.
Having not actually witnessed the defendant at the scene, the expert witness can not state for a fact that the sample is a match to the defendant, particularly when the samples were collected at different times and different places by different collectors using different collection methods. Ultimately, the testimony of expert witnesses is regarded as supportive of evidence rather than evidence in and of itself, and a good defense attorney will point out that the expert witness is not in fact a witness to anything, but rather an observer.
When a witness is asked a question, the opposing attorney can raise an
objection, which is a legal move to disallow or prevent an improper question to others, preferably before the witness answers, and mentioning one of the standard reasons, including:
* argumentative
* asked and answered
*

Immaterial refers to evidence that is probative, but not as to any fact material to the case. See Black's Law Dictionary, 7th Ed.).

, an attorney often had to follow an objection with an exception to preserve the issue for appeal. If an attorney failed to "take an exception" immediately after the court's ruling on the objection, he waived his client's right to appeal the issue. Exceptions have since been abolished, due to the widespread recognition that forcing lawyers to take them was a waste of time.

, testimony is a proposition conveyed by one entity (person or group) to another entity, whether through speech or writing or through facial expression, that is based on the entity's knowledge base. The proposition believed on the basis of a testimony is justified if conditions are met which assess, among other things, the speaker's reliability (whether her testimony is true often) and the hearer's possession of positive reasons (for instance, that the speaker is unbiased).
We can also rationally accept a claim on the basis of another person's testimony unless at least one of the following is found to be true:
# The claim is implausible;
# The person or the source in which the
claim is quoted lacks
