Pierce Butler, Rockford Life Insurance Company v…
“ In reason the cost of depreciation, like other items of expense to be deducted, ought to be limited to that related to the income taxed. Allowance of deduction of expenses incurred for the correction of premiums or in respect of other income not taxed would be hard to justify. In absence of specific declaration of that purpose, Congress may not reasonably be held to have intended by that means further to reduce taxable income of life insurance companies. ”
