Sole discretion意思
"Sole discretion" is a legal term that means the exclusive right to make a decision or take action without the input or interference from others. When something is done at the sole discretion of an individual or entity, it means that they have the unrestricted authority to decide what action to take, without needing the approval or consent of anyone else.
For example, a contract might give a manager the sole discretion to decide whether to approve a budget request, or a company policy might give the CEO the sole discretion to hire and fire employees. In these cases, the manager or CEO can make these decisions on their own, without needing the approval of a board, committee, or other individuals.
