Client Alert: Jurisdictional Win Shields Businesses From Texas State Securities Board Overreach

The Texas State Office of Administrative Hearings (SOAH) set aside an Emergency Cease Order issued by the Texas State Securities Board (TSSB) against Billionico Academy, Auratus, and related respondents in Texas State Securities Board v. Billionico Academy et al. (SOAH Docket No. 312-25-18829). The decision, based on a lack of personal jurisdiction, underscores robust protections for nonresident entities and individuals operating in the cryptocurrency and global business sectors.  

Client Alert: The End of Chevron Bias: A Tombstone No Federally Regulated Company Should Miss

For companies whose operations are subject to strict federal regulations – and particularly those that are facing or may be facing enforcement actions – take note. The U.S. Supreme Court may have just leveled the playing field. On Friday, June 28, 2024, the Supreme Court overturned a long-standing legal precedent that instructed courts to defer to federal agencies’ interpretations of ambiguous laws they administer. Instead, federal laws will be interpreted by the courts. Federal agencies will need to prove their cases, including enforcement actions where an arguably ambiguous statute is at issue. This is good news for businesses in the U.S.

Client Alert: New For 2024 - The Answer to Two Important Questions Every Rental Property Owner in Virginia Needs to Know about Changes to the Virginia Residential Landlord Tenant Act (VRLTA)

The Virginia Residential Landlord Tenant Act, commonly referred to as the VRLTA, was initially enacted in 1974 and is a set of laws that govern the rental of certain residential property in the Commonwealth of Virginia. In addition to other obligations set forth therein, the VRLTA establishes the rights and responsibilities of both landlords and tenants in a residential lease agreement governed thereby. The VRLTA provides a clear legal framework for resolving disputes and to ensure fairness in those rental agreements. The VRLTA is amended from time to time, and it is important to understand those changes to ensure continued compliance.

Client Alert: IRS Will Determine Whether PPP Loans Properly Forgiven, Treat Improperly Forgiven Amounts as Income

As one of the authors noted in a previous alert, “the CARES Act provided that the forgiven amounts of Paycheck Protection Program (“PPP”) loans would not be includable in a PPP borrower’s gross income at the federal level, and subsequent legislation provided that expenses paid with PPP funds would still be tax deductible.”  Recent non-precedential guidance from the IRS’s Office of Associate Chief Counsel, however, has concluded that only properly forgiven amounts will not be treated as gross income by the IRS.  In short, the IRS intends to reach its own determination regarding the propriety of the decision of the U.S. Small Business Administration (“SBA”) to forgive PPP loan amounts.

Client Alert: Don’t Jeopardize Your PPP Forgiveness Appeal

Recently, we’ve been hearing from clients that their Paycheck Protection Program (“PPP”) loans are being reviewed by the Small Business Administration ("SBA") and we are here to help respond to SBA inquiries and requests for information. This Client Alert discusses the Interim Final Rule (“IFR”), effective September 14, 2021, promulgated by the SBA detailing the procedures for appealing adverse PPP forgiveness determinations. Note that these will only become relevant if the SBA formally denies (in whole or in part) a PPP forgiveness application by the delivery of a final SBA loan review decision document.
