During court hearings, some witnesses are allowed by the judge to give their evidence without being present in court or without being seen by everyone in court.
In such cases, "special measures" are introduced which might involve a witness testifying from behind a screen so only the judge, jurors and barristers can see them, or by video-link from somewhere outside the courtroom.
The central purpose of "special measures" is to make it less stressful for witnesses to give their evidence.
The measures can be applied to witnesses for either side - the prosecution and the defence - and the kind of cases in which they can be used are set out in guidance by the Crown Prosecution Service.
They include trials in which people allege they've witnessed serious violence or been the victim of a sexual offence.
Those who are assessed as "vulnerable" - if they're under 18, have a mental health problem or disability - may also be permitted to testify from behind a screen or by video-link.
A variety of other types of "special measures" are also available, such as hearing evidence without the public being present - but this is applied less often.

"No," the witness replied.
"You are quite close friends with Svenson aren't you? And we know at about 21:20, a girl was killed in Harold Hill - and he never told you?"
"No," the witness replied.
"There is a call just after the girl died between you and Svenson for 50 seconds - did he say anything about that to you?"
"No," the witness replied.
"Did Svenson seem different at all to you during the call?"
"No," the witness said.
At 20:11 on 1 March, the witness booked a mini-cab with A1 Minicabs for Mr Ong-a-Kwie.
The records held by A1 cabs show that the witness booked the taxi under his own name to be taken to Chippenham Road in Harold Hill.
"Did Svenson ask you to book the taxi under your own name?", Ms Forshaw asked.
"No," the witness replied.
"Had you booked a taxi for Svenson before?", she asked.
"Yes," he replied.
The 17-year-old witness has continued giving evidence following Monday's delay.
Sarah Forshaw QC, for Manuel Petrovic, told jurors that the witness was friends with Svenson-Ong-A-Kwie, 19, for a number of years.
A number of texts were passed between the witness as Mr Ong-a-Kwie on 1 March.
"Where you trying to arrange to meet him?", Ms Forshaw asked.
"Yeah we were going to meet", he replied.
A screen is being put in place for the first witness of the day, who cannot be named for legal reasons.

Prior to that Richard Baxter - a phone data analyst - entered the witness box to explain to the jury why relevant cell site data was relevant in trials.
He said: "When your mobile phone switches on and is being used to make calls or texts this will go through a mast - usually the closest one to the phone.
"There are only four networks - EE, Vodafone, Three and 02.
"Police can go to these four networks and find information including billing information and cell site information used to plot the movements of a phone."
Using cell data Mr Baxter was able to outline Svenson Ong-a-Kwie's movements after leaving the cafe until later that evening on 1 March. The data placed Mr Ong-a-Kwie in various locations including the Amy's Park area.
A 17-year-old boy was later called as a witness and he said he booked a cab for Mr Ong-a-Kwie - something he did "for all my mates", he told the court.
After Mr Ong-a-Kwie's arrest, the teenager told jurors he deleted his number from his phone.
