The Court of Appeals’ decision in in Cemex Construction Materials South, LLC v. Falcone Bros. & Assoc., Inc., 237 Ariz. 236 (App. 2015), which is the subject of this post from May 2015, will cease being good law on August 6, 2016. The case was legislatively overruled by HB 2268, which was signed into law by Governor Ducey on May 12, 2016 and will become effective on August 6, 2016. My post on the effects of HB 2268 and its overruling of the Cemex decision can be found here.

In Ramona Equipment Rental, Inc. v. Carolina Casualty Ins. Co., et al., Case No. 12-55156 (June 20, 2014), the United States Court of Appeals for the Ninth Circuit recently addressed for the first time the issue of when a 90-day Miller Act notice needs to be served for materials and/or equipment furnished on an open book account. Consistent with decisions from the First, Fourth, and Fifth Circuits, the Ninth Circuit held “that if all the goods in a series of deliveries by a supplier on an open book account are used on the same government project, the ninety-day notice is timely as to all deliveries if it is given within ninety days from the last delivery.”
