1.法律文件中可能会有“Blue pencil”，它的意思不是“蓝铅笔”，而是“修改、删除”

示例：He kept careful records of the blue pencil, showing passages excised as a condition of licensing.

他小心地保存着修改记录，出示那些像种许可的篇章。

2.“Blue pencil rule”，即“蓝铅笔原则”，合同中的一种原则。为保持合同整体的合理性，法官可宣布部分合同条款无效，而剩余条款仍保持有效。

示例：Blue Pencil. If any court determines that the covenants contained in this Section 8, or any part hereof, are unenforceable because of the duration or geographic scope of such provision, such court shall have the power to reduce the duration or scope of such provision, as the case may be, to as close to the terms hereof as shall be enforceable and, in its reduced form, such provision shall then be enforceable.

蓝铅笔原则。如果任何法院因条款地理范围或时长认为第8条条款或该合同任何部分不可执行，该法院有权视情况而定减少此类条款的地理范围或时长，使该条款尽可能接近其本意且可执行；修改后的此类条款应可执行。
