・individual judgment
・personal decision

「個人判斷」英語叫做 individual judgment 或 personal decision 來表達。

From March, wearing a mask has been entrusted to individual judgment.
（從三月開始，是否戴口罩已交由個人決定。）

Of course, this is not mandatory. Whether or not to participate is a personal decision.
（當然，這不是強制性的。是否參與是個人的決定。）
