Doctrine of Blue Pencil:—
The “doctrine of blue pencil” was evolved by the English and American courts. (See Halsbury’s Laws of England, (4th Edn., Vol. 9), p. 297, para 430) (Para 10). This doctrine holds that if courts can render an unreasonable restraint reasonable by scratching out the offensive portions of the covenant, they should do so and then enforce the remainder. Traditionally, the doctrine is applicable only if the covenant in question is applicable, so that the unreasonable portions may be separated, EPI of Cleveland Inc. v. Basler [12 Ohio App 2d 16: 230 NE 2d 552, 556].
