Final answer:
When a defendant refuses to speak in court after hearing the charges against them, the court will typically enter a plea of 'not guilty' on their behalf.
Step-by-step explanation:
When a defendant appears in court for arraignment and refuses to say anything after hearing the charges against them, the court will usually enter a plea of 'not guilty' on their behalf.
This occurs because the defendant has the right to remain silent and not incriminate themselves. By remaining silent, they are essentially indicating that they do not admit to the charges and wish to contest them.
It is important to note that the court may enter a different plea if the defendant's refusal to speak is interpreted as a form of admission or guilt.
