Being witness is a formal position

Being a witness is a formal position in the process of law. To accept being a witness is a conscious choice to want to be present and testify. A witness has to be sworn in by taking an oath.

One can also be called into the court, in which case one is obliged to come and to take an oath as well. Being a witness is a formal position for which one has to accept responsibility. As a witness, lying is a crime. If you are called into the court, you have to come. If you do not, it is a crime as well. However, a witness does not have to incriminate her or him self. Loss of memory or forgetfulness is accepted by the court as a reason for not having to testify. Also the witness capacity to speak the truth can be hindered by relations to other people who are involved as well.
