In the Coastal Oil case, what was the main issue raised by Garza Energy Trust?

The main issue raised by Garza Energy Trust in the Coastal Oil case was the allegation of trespassing while hydraulic fracturing. This indicates that Garza Energy Trust claimed that Coastal Oil encroached upon their property rights while engaging in hydraulic fracturing operations. Trespassing in this context implies that Coastal Oil allegedly conducted its drilling activities without proper authorization or consent from Garza Energy Trust, which is a significant legal concern when dealing with property and mineral rights.

This issue underlines the principle that landowners have rights concerning the use of their property, and it emphasizes the legal implications of activities like hydraulic fracturing, especially when they extend beyond the boundaries of the land owned or leased by a company. Trespassing can lead to legal disputes over the extent of property lines and the rights associated with resources located underground. Thus, the focus on trespassing illustrates the complexities involved in energy extraction and property law, highlighting the importance of proper leasing and permission for any drilling activities.
