When the name of any person out of this state or incapable of giving consent to the bringing of a writ of error or taking of an appeal is omitted in the writ of error or appeal, and the cause proceeds without his name, his rights shall not be impaired by the judgment on the writ of error or appeal, and he may bring his separate writ of error or appeal in the same manner as if no former writ or appeal had been brought.
