Administrative
FERC ratemaking that substituted a second time period was arbitrary and capricious in that insufficient explanation was offered for the selection of the second period.
No error in agency's declining to index the rates across a period of time, as it would have resulted in an unreasonable benefit, and the purpose of the indexing regulation is equitable.
Corporations and partnerships must be evenly treated in deciding tax offsets.
