Joining an Austrian VIAC arbitration: non-signatory third party, jurisdiction and fees

A non-signatory third party is not automatically added as a party to an ongoing VIAC arbitration merely because it is economically affected by the dispute. Under Article 14 of the Vienna Rules, a party or the third party itself may request joinder. The arbitral tribunal decides the request after hearing all parties and the third party and considering all relevant circumstances.

The review has three separate levels: the scope of the arbitration agreement under section 581 ZPO, the tribunal’s jurisdiction under section 592 ZPO and the procedural joinder mechanism under Article 14 of the Vienna Rules. The missing signature is an important circumstance, but it does not answer every jurisdiction question by itself.

A missed challenge of an arbitrator concerns a different procedural issue and is not developed here. Conflicting general terms and arbitration clauses are also a separate preliminary question concerning formation of the arbitration agreement.

This article deals only with joining a non-signatory third party to ongoing institutional proceedings. General multi-party arbitration, the appointment of arbitrators and consolidation of separate proceedings are distinct issues.

Starting point: arbitration agreement and third party

Section 581 ZPO links an arbitration agreement to specified disputes arising from a contractual or non-contractual relationship. The first step is therefore to identify the relationship named in the clause and the third party’s role in it. An economic interest in the outcome does not by itself describe that legal relationship.

The main contract, amendments, incorporated terms, guarantees and ancillary agreements must be reviewed. The question is whether they establish a sufficient connection between the third party, the dispute and the arbitration agreement. The topic page on reviewing an arbitration clause explains this initial contract review.

What a request under Article 14 must contain

Article 14 paragraph 2 of the Vienna Rules requires the third party’s full name and contact details, the grounds for joinder and the requested manner of joinder. The request must show why this person or company should be included and which procedural position it seeks.

If the request is made with the statement of claim, it is submitted to the VIAC Secretariat. The Secretariat transmits the statement of claim to the third party and the other parties for comments. A request made during the arbitration is addressed to the tribunal. The procedural stage affects which participation rights can still be exercised in practice.

Hearing and decision by the arbitral tribunal

Under Article 14 paragraph 1, the tribunal decides whether and how the third party is joined. Before doing so, it hears all parties and the third party seeking or facing joinder. The decision must consider the relevant circumstances. These may include the contractual relationships, the common dispute, the third party’s role and the stage of the arbitration.

The hearing gives the third party an opportunity to respond to the joinder and its proposed scope. It does not remove the need to examine whether the tribunal has jurisdiction over that third party. Consent, objection, request and jurisdiction arguments should therefore be documented in separate statements.

How jurisdiction over the third party is reviewed

Under section 592 ZPO, the arbitral tribunal decides on its own jurisdiction. Jurisdiction may extend to the arbitration agreement and the dispute covered by it. Where the third party did not sign the original clause, the review must identify the basis relied on for joinder and whether that basis covers the particular dispute.

Jurisdiction and procedural convenience are separate questions. A third party may be important to the merits without already being a party to the arbitration agreement. Conversely, a contractual connection may exist even though the signature does not appear on the same document. The complete contractual chain and the parties’ conduct must therefore be considered together.

Under section 592 ZPO, a jurisdiction objection generally must be raised no later than the first submission on the merits. Where the third party joins later or a new dispute is introduced, the relevant point in time must be established from the procedural file. The article on an untimely jurisdiction objection explains this procedural issue separately.

Procedural status and participation rights

The request must distinguish between joining as a party and another form of participation. The requested status affects relief, objections, evidence applications, service and costs. The third party should therefore state its procedural role, not only its economic connection with the dispute.

If a third party is joined under Article 14 with a statement of claim and no arbitrator has yet been appointed, it may participate in constituting the tribunal under the rule. If the tribunal refuses a request made with the statement of claim, it may return the statement of claim and request to the Secretariat for separate treatment. This is why the request and the appointment timetable must be coordinated.

Joinder is distinct from consolidating separate proceedings. Article 15 of the Vienna Rules concerns consolidation and has its own requirements. The article on consolidating VIAC arbitrations addresses that different situation.

Registration fee and advance for joinder

Under Article 10 paragraph 1 of the Vienna Rules, the requesting party must pay a registration fee for a request to join a third party. The fee is separate from the advance on costs. Where more than two parties are involved, Article 10 paragraph 2 allows an increase of ten percent for each additional party up to a maximum of fifty percent.

For a joinder request, the Secretary General may fix a separate advance under Article 42 paragraph 3. Article 44 paragraph 7 also permits administrative and arbitrator fees for the request to be calculated separately. The amount depends on the circumstances of the case and the applicable schedule of fees. A reliable assessment therefore requires the request, amount in dispute, procedural stage and proposed status of the third party.

The costs issue is relevant before the joinder decision. The article on the VIAC advance on costs explains what can happen when an allocated share is not paid. Final allocation of costs is a separate matter under Article 38 of the Vienna Rules and, where applicable, section 609 ZPO.

Why joinder affects the later costs decision

Article 44 paragraph 4 of the Vienna Rules provides for an increase in the listed administrative and arbitrator fees of ten percent for each additional party, up to fifty percent. For a joinder request, Article 44 paragraph 7 may allow a separate calculation. These provisions describe procedural costs and do not replace a case-specific calculation.

The final decision on who bears the costs follows separately. Under Article 38, the tribunal decides on costs and their allocation upon request. It may consider the conduct of the parties and their contribution to efficient and cost-effective proceedings. Joinder therefore does not automatically determine the final costs burden, and paying an advance does not settle that question.

Documents and chronology for the joinder request

The first review should include the main contract, arbitration clause, amendments, incorporated terms, guarantees and documents showing the third party’s role. Also collect the statement of claim, answer, previous requests, service records, tribunal orders and correspondence with the VIAC Secretariat.

Prepare a short chronology covering signature, contractual participation, the third party’s first involvement, commencement of the arbitration, constitution of the tribunal and the intended joinder request. Record whether the third party is to participate as a party, an intervenor or in another capacity. The page on preparing arbitration proceedings explains how dispute, evidence and timetable fit together.

Common questions about a non-signatory third party

Can a non-signatory third party join a VIAC arbitration?

Article 14 of the Vienna Rules allows a party or the third party to request joinder. The tribunal hears all parties and the third party and considers the relevant circumstances. Whether jurisdiction extends to the third party must also be reviewed against the arbitration agreement and the specific dispute.

Who decides whether the third party is joined?

The arbitral tribunal decides the joinder and its form in an ongoing VIAC arbitration. The request must identify the third party, the grounds and the requested manner of joinder. A request made with the statement of claim is subject to specific transmission and procedural rules.

What fees can arise from joinder?

Article 10 of the Vienna Rules provides for a registration fee for the request. A separate advance may be fixed under Article 42 paragraph 3, and Article 44 paragraph 7 permits separate calculation of administrative and arbitrator fees. The amount depends on the case, amount in dispute and procedural stage.

Next step

Contract, arbitration clause, correspondence and deadlines should be collected. It can then be assessed whether negotiation, preservation or arbitration is central.
