In court proceedings, deadlines are crucial – if a party fails to raise an objection on time, it will usually lose the right to do so later in the process. However, a new interpretative decision of the Bulgarian Supreme Court of Cassation (SCC) introduces an important clarification: in certain cases, a third party involved in the proceedings on the defendant’s side may raise objections that the defendant itself failed to make. The ruling is significant for many civil and commercial disputes, as it broadens the possibilities for legal defence in court proceedings.
Bulgarian civil procedure law provides clear and specific deadlines within which the parties may perform procedural actions. Actions taken after the expiry of the relevant deadline are generally disregarded by the court unless they fall within expressly предусмотрени exceptions. Nevertheless, questions sometimes arise regarding the scope and application of certain procedural institutions, which require an interpretative ruling by the Supreme Court of Cassation.
With its Interpretative Decision dated 11 May 2026, the SCC held that a third-party intervener supporting the defendant may raise objections against the claim even after the deadline for filing the statement of defence has expired, provided that the objections had become precluded for the defendant. The only exception is where the third party voluntarily chose to join the proceedings.
How disputes begin and what deadlines apply
Court proceedings begin with a claim filed by a party alleging that its rights have been violated. The claim is brought against a specific person who, once served with the statement of claim, has one month to submit a response.
In that response, the defendant must set out its objections and requests. If the defendant fails to do so within the statutory period, it loses the opportunity to raise them later in the proceedings.
Within the same deadline for responding to the claim, the defendant may request that the court involve a third party who is not initially participating in the dispute. This is possible where the third party has an interest in the final judgment being rendered in favour of the defendant. In such cases, the third party joins the proceedings on the defendant’s side regardless of its own will. Once approved by the court, the third party becomes an independent participant in the proceedings.
What rights does the third party have?
The third party has the right to undertake almost all procedural actions, except those that could result in the premature termination of the proceedings.
A practical issue arises when the third party is joined after the defendant’s deadline for presenting objections and evidence has already expired. This raised the question of whether the newly involved third party could make objections or requests that the defendant could have made, but failed to raise in time.
This is precisely the issue addressed by the SCC in its new interpretative ruling. The Court’s answer is affirmative – a third party joined on the defendant’s side may raise objections against the claim even if the defendant itself failed to do so within the statutory deadline.
When does this rule not apply?
The SCC also establishes an important exception. If the third party voluntarily joins the proceedings on its own initiative, it may not raise objections that have already become time-barred for the defendant.
In such cases, the voluntarily intervening party may only undertake procedural actions for which the applicable deadline has not yet expired.
Why is this decision important?
The SCC’s interpretative ruling provides broader opportunities for defence in court proceedings and clarifies an issue on which contradictory case law previously existed.
The decision may have substantial implications in complex civil and commercial disputes, especially where several interested parties are involved and the defendant’s defence depends on the actions of third parties joined in the proceedings.
