Questão jurídica principal
Whether the utility qualifies for partial exemption from direct federal tax as a private-law company pursuing public purposes.
Decisão extraída
No. Although it performs a public supply task, its overall activity is primarily profit-oriented, so the public-purpose exemption does not apply.
Fundamentação extraída
The company is a private-law joint-stock company with a broad commercial purpose, profitable operations, price-setting freedom, and no statutory guarantee that profits are exclusively and irrevocably devoted to public purposes; the economic aim clearly prevails.
