Tom C. Clark,
Paragon Jewel Coal Company v. Commissioner of Internal Revenue…
“ An economic interest is possessed in every case in which the taxpayer has acquired by investment any interest in mineral in place or standing timber and secures, by any form of legal relationship, income derived from the extraction of the mineral or severance of the timber, to which he must look for a return of his capital. But a person who has no capital investment in the mineral deposit or standing timber does not possess an economic interest merely because through a contractual relation he possess (es) a mere economic or pecuniary advantage derived from production. ”
