Tenneco West, Inc. v. County of Kern

Citations: 194 Cal. App. 3d 596; 239 Cal. Rptr. 612; 96 Oil & Gas Rep. 446; 1987 Cal. App. LEXIS 2073Docket: F006433

Court: California Court of Appeal; August 28, 1987; California; State Appellate Court

Narrative Opinion Summary

The case involves an appeal by Tenneco West, Inc. against a judgment favoring the County of Kern and its Assessor regarding ad valorem property taxes assessed on gas storage rights in the Ten Section Oil and Gas field. The dispute originated from a decision by the Kern County Assessment Appeals Board, which denied Tenneco's request for a reduction in the taxable value of these rights for the 1978-1979 tax year. Tenneco argued that the assessments violated Proposition 13, which limits property tax increases and reassessments to instances of ownership change or new construction. The court found that the gas storage rights, although not previously assessed, were a taxable interest that gained value before the 1978 lien date, warranting a separate valuation. The court further upheld the application of Rule 468, which permits the assessment of oil and gas properties based on changes in reserves and ensures compliance with Proposition 13. The ruling affirmed the county's assessment, recognizing the unique nature of gas storage rights and their valuation as analogous to oil and gas production rights. Consequently, the court upheld the assessor's valuation, awarding costs of the appeal to the county and assessor.

Legal Issues Addressed

Application of Proposition 13 to Property Valuation

Application: The court applied Proposition 13 to limit the assessment powers, emphasizing that rights inherent in property ownership do not warrant new assessments unless a change of ownership or new construction occurs.

Reasoning: The court found this reasoning flawed, stating that Proposition 13 limits the assessment powers and that the right to use the property for storage is an inherent attribute of ownership, thus not warranting a new assessment under the circumstances presented.

Assessment of Newly Discovered Property Interests

Application: The court validated that newly discovered property interests should be taxed in the year they gain value, establishing a base year for future assessments.

Reasoning: Under California Administrative Code, gas storage rights are assessed at market value upon their discovery, similar to other resource additions.

Rule 468 and Valuation of Oil and Gas Reserves

Application: Rule 468 was applied to assess the value of oil and gas reserves, allowing for adjustments due to changes in property rights and ensuring compliance with Proposition 13.

Reasoning: Rule 468, adopted by the State Board of Equalization, applies 1975 base values to 'proven reserves' and current values to 'additions to reserves.'

Valuation of Gas Storage Rights

Application: The court addressed the valuation of gas storage rights, concluding that these rights are analogous to oil and gas production rights and should be assessed based on their discovery and market value.

Reasoning: The Kern County Assessor's valuation of gas storage rights following their discovery was lawful, and the Kern County Superior Court's affirmation of the assessment appeals board's decision was upheld.
