The complainants stated that if Sempra Energy operations were set-up in full compliance with Mexican law that it would have to pay an addition 8 billion pesos in taxes. (http://www.tiempoenlinea.com.mx/
In the matter of fiscal fraud, the authorities need to determine why alleged taxes are not paid when profit is being generated on Mexican soil.

The legal problems of Sempra have also extended into the U.S. District Court of Southern California after Judge Cathy Ann Bencivengo ruled in favor of Ramirez Ritchie regarding the dispossession land by Sempra Energy. Judge Bencivengo ruled that trial regarding the dispute will take place in the U.S. after an examination of court documents. (http://www.jornada.unam.mx/
Sempra Energy has had problems with its public image in Mexico most notably following the an investigation by Mr. Fausto Ovalle, a reporter for online newspaper La-ch.com who published the article: "The Secret of Sempra Energy" where he stated that “For ten years, the Baja Federal Electricity Commission (CFE) held a contract with Sempra Energy which made them lose 240 million pesos. The problem was that the CFE purchased and paid for natural gas from Sempra Energy and if they did not use the natural gas , then Sempra, with all the honor of a pig in a sty, bought back the surplus at a 20% reduction in price. Sempra Energy, always finding deceitful, dishonest ways to add (steal) to their unearned wealth.”
