Read the following excerpt from a US court opinion:
```
judgment with respect to Cerezo’s Title VII and Law 100 hostile work environment claims is DENIED. Finally, a genuine dispute of material fact exists as to whether Cerezo had obtained proper authorization for his extended vacation period, and, therefore, whether Ferrovial had just cause to terminate his employment. Ferrovial’s motion for summary judgment with respect to Cerezo’s Law 80 claim is therefore DENIED. IT IS SO ORDERED. 1 . Defendant failed to file a reply to plaintiffs opposing statement of uncontested material facts contained in Docket No. 15-1. Because the additional facts alleged in plaintiff's opposition were supported by citations to appropriate record materials, see Goldman, Antonetti, Ferraiuoli, Axtmayer & Hertell v. Medfit Int’l, Inc., 982 F.2d 686 (1st Cir. 1993) , those facts are deemed admitted by defendant
