William O. Douglas,
Real Estateland Title Trust Company v…
“ To be sure, reasons of economy may cause a management to discard a title plant either where it has become outmoded by improved devices or where it is acquired as a duplicate and therefore is useless. But not every decision of management to abandon facilities or to discontinue their use gives rise to a claim for obsolescence. For obsolescence under the Act requires that the operative cause of the present or growing uselessness arise from external forces which make it desirable or imperative that the property be replaced. ”
