Sitting behind glass docks is more common in the UK, France, Canada and former Soviet-bloc countries, but from as early as 1914 American courts have found that any form of constraint undermines the defendant’s right to a fair trial.

To test this theory, researchers carried out an experiment at the Sydney West trial courts. More than 400 mock jurors watched a 45-minute live trial about an alleged terrorist conspiracy, with actors playing the judge, counsel, witnesses and defendants. Researchers then swapped the position of the accused for different “juries” to see if it had a bearing on their decision, with the accused either at the Bar table, in an open dock or in a glass dock.

“The judges who found that glass docks create prejudice have been proved right,” says Prof David Tait. “What surprised us was the size of the difference, and the way even ordinary docks make defendants look guilty.”

In the study, 60% of jurors who saw the...
