A more thorough explanation:

Definition: In Scots law, being at the horn refers to being declared an outlaw and having a public proclamation made against you. It is also known as "put to the horn."

Example: If someone owes a debt and fails to pay it despite being ordered to do so by a court, they may be put to the horn. This means that a public proclamation will be made against them, and they will be declared an outlaw until they pay the debt.

Explanation: The example illustrates how being at the horn is a legal consequence for failing to comply with a court order. It is a serious punishment that can have significant consequences for the individual involved.
