burden of proof

In court, the responsibility to come forward with credible evidence that a thing happened or did not happen.Normally,the party who complains about a wrongdoing has the burden of proof. In some circumstances, primarily under federal laws related to discrimination, the aggrieved party need only make an allegation of wrongful behavior and the defendant has the burden of proof that his or her behavior was reasonable under the circumstances.The burden of proof may be set at different levels for various types of litigation. For example:

• When contesting a property tax valuation, the owner must generally prove that the assessment was manifestly excessive, clearly erroneous, or confiscatory. This burden of proof is very high, much more than required to show the assessment was simply inaccurate.

• Housing discrimination cases involve a three-step process that moves the burden of proof back and forth. Under what is called the McDonnell Douglas test, plaintiffs have the burden of showing they are a member of a protected minority; they applied for and were qualified to rent or purchase property; and they were rejected and the housing or rental opportunity remained available afterward. That creates a presumption of discrimination, which shifts the burden to the defendants to prove they had legitimate, nondiscriminatory reasons for their actions. If successful, the burden shifts back to the plaintiffs to prove by a preponderance of the evidence (meaning, “more likely than not”) that the offered reason was a pretext and there really was a discriminatory purpose.
