– Main areas of practice –

In the field of commercial law Claus Casati deals in depth with:

Public procurement law
Competition law issues (state aid law, issues of intellectual property law, in particular in the area of services of general interest, antitrust law and intellectual property law)
Public passenger transport issues (Motor Vehicles Act, Railway Act, ÖPNRV-G and PSO Regulation 1370/2007)
Public law matters (in particular trade law, data protection, waste management law, rescue services and art restitution law)
Civil law matters (in particular commercial agency law, construction and contract law)

Public procurement law

Casati has been intensively involved in public procurement law issues since 1995. He wrote his dissertation on the subject of “Non-procurement aspects of public procurement, in particular taking into account countertrades” at the University of Vienna, under the supervision of Prof. Dr. Korinek and Prof. Dr. Aicher.

In addition to numerous publications and many lectures, Casati continuously assists numerous public clients in the handling of contract award procedures, including the preparation of all tender documents required for this purpose (in particular also the required performance contracts).

In addition, he represents numerous bidders/applicants in proceedings before public procurement authorities and civil courts.

His many years of dealing with public procurement law issues in all details and from all perspectives, combined with his economic expertise, enable him to communicate complex matters in a simple manner, to successfully conclude public procurement control proceedings for his clients, and to handle public procurement procedures in the best possible manner (largely without friction). Economic expertise coupled with many years of procurement-specific know-how guarantee the best possible advice and representation.

A particular focus of our procurement law practice is in the areas of municipal water management, waste management, public transport, the procurement of IT services including complex software programs, and construction projects (especially in the context of functional tenders).

Competition law

Advice and support for the public sector on issues relating to the design of services of general interest in conformity with competition law, in particular on issues relating to the design of waste and wastewater disposal and local public transport in conformity with competition law. In addition, we provide ongoing advice and support to the public sector on issues relating to the granting of financial resources in conformity with Community law, as well as on issues relating to the notification of individual aid and state aid regulations. Casati also advises and represents companies/public institutions in connection with obtaining subsidies/aid and their approval by the Commission and national courts/authorities.

Casati is, inter alia, a lecturer on the subject of state aid law at the University of Applied Sciences of the Vienna Vocational Training Institute.

Next to questions of state aid law, (antitrust) regulations concerning companies with market power have to be taken into account when consulting. This applies to both public companies and private companies, especially in the petroleum industry. Here, Casati advises gas station tenants against the mostly market-powerful mineral oil companies with regard to antitrust issues as well as questions of commercial agency law.

Casati is also active in the area of unfair competition, whether in connection with public procurement law, or in connection with companies with market power, or as part of the day-to-day competition between private individuals. The best possible legal security is provided by prophylactic control and advice in competition law matters. The answering of general competition law questions, a brief look at intended packaging/advertising campaigns are all part of Casati’s field of activity.

The Casati team is also happy to assist you in areas of intellectual property law. Trademarks, inventions, intellectual-creative works and designs have become an integral part of today’s business life. Here, too, prophylactic advice protects and creates value. The Casati team will be happy to assist you with:

Trademark applications
Design patent applications
Conception and negotiation of license agreements, especially in the software sector
Examination of possible interferences
Mediation of (patent) attorneys

Public passenger transport

Long-standing assistance to public authorities on public transport issues in theory and practice. Casati deals with issues related to the Community-compliant financing of transport companies, the Community-compliant award of transport service contracts and the granting of concessions for the operation of motor lines and railroads. To this end, he has conducted various procurement procedures for (sector) contracting authorities and also assists private railroads in particular with the various procurement projects (from the procurement of rolling stock to the repair of rail infrastructure).

Public law

Public law covers innumerable administrative matters. In addition to knowledge of the relevant Community law, it requires profound knowledge of Austrian constitutional law, administrative procedural law and the respective administrative material laws. An intensive education in the field of public law (Casati was a trainee lawyer and substitute of Univ. Prof. DDr. Walter Barfuß for more than 5 years) have made him an intensive connoisseur of public law. In particular, he has had the opportunity to work intensively in the following administrative fields and to acquire considerable know-how:

Rescue services (ongoing support of various providers of ambulance and rescue services, such as representation before the ECJ in case C- 76/97 Tögel/NÖGKK)
Data protection law (handling of numerous data protection law issues as well as lecturer at BFI Vienna on the topic of “data protection law”)
Trade Regulation Act (questions of the Trade Regulation Act and related ancillary laws arise in proceedings under public procurement law and competition law as well as in daily counseling)
Art Restitution Act (the Austrian Art Restitution Act authorizes the Federal Minister of Education, Science and Culture to return art objects looted by the Nazi regime to their former owners or their legal successors. Casati deals with related issues, in particular those of international inheritance law)
Waste law (questions concerning the licensing of plants according to the Waste Management Act and the shipment of waste abroad are part of the ongoing legal practice)

Civil law

The core of almost every legal activity is a profound knowledge of civil law. Questions of civil law have to be answered/regulated above all in the context of award procedures. Primarily, the daily consulting business requires answers to civil law questions, especially in the drafting of contracts. Thus, above all, the drafting of contracts is part of our daily business (in particular the drafting of general terms and conditions, supply and service contracts as well as real estate contracts).

In addition to the drafting of contracts, the following civil law issues are among Casati’s main areas of practice:

Agreements in the field of information technologies of all kinds, including agreements on the creation/use of complex software programs
Distribution agreements, such as gas station leases
Construction contracts (supplements to the relevant ÖNORM standards and their interpretation and practical application)
Real estate purchase agreements/leases

If you are of the opinion that the processing of your personal data by us violates applicable data protection law or that your data protection claims have been violated in any other way, you have the option of complaining to the competent supervisory authority. In Austria, the data protection authority is responsible for this.

Data security

Your personal data is protected by appropriate organizational and technical precautions. These precautions relate in particular to protection against unauthorized, illegal or even accidental access, processing, loss, use and manipulation.

Notwithstanding our efforts to maintain an appropriately high level of due diligence at all times, it cannot be ruled out that information you disclose to us via the Internet may be viewed and used by other persons.

Please note that we therefore accept no liability whatsoever for the disclosure of information due to errors in data transmission not caused by us and/or unauthorized access by third parties (e.g. hacking attack on e-mail account or telephone, interception of faxes).

Use of the data

We will not process the data provided to us for purposes other than those covered by the mandate agreement or by your consent or otherwise by a provision in accordance with the GDPR. This excludes the use for statistical purposes, provided that the data provided has been anonymized.

Disclosure of data breaches

We strive to ensure that data breaches are identified at an early stage and, if necessary, reported to you or the relevant supervisory authority without delay, including the respective categories of data affected.
