A month with Seconda

What's new at Seconda?


Seconda is celebrating its 2nd anniversary!
Surrounded by our Seconds, clients, partners and Seconda lovers (there, I said it!), we had a wonderful evening at the Grand Quartier Hotel on Thursday, June 19th!
We heard bursts of laughter, the clinking of glasses, and heated debates, whether on the importance of formalities in civil procedure, the nature of a company (contract or structure), or even the best places to walk your dog…
And faces were put to the files: the seconded staff met their seconded staff!

This evening was an opportunity to take stock of Seconda's second year: successes, encounters, victories, but also, in all honesty, our few failures or moments of solitude :)
We covered everything, including of course our big ambitions for the future!
We thank all those who were able to be present and we apologize to our muses (Mylène Bernardon, Anastasia Pitchouguina and Serge Vatine) who were detained by our profession, which is as beautiful as it is engaging.
We repeat, this is only the beginning…we eagerly await what's next!
Coming in July: Seconda co-hosts a webinar with Artur'in on July 8th and is preparing for the summer period!

Marie is our expert in customs law
Secondant of the Month
This month, we present Marie Fernet !
A lawyer and doctor of law, practicing mainly in customs law, Marie was propelled into the spotlight following the announcements on customs duties by the American president last April!
Marie is delighted that customs law, long under-regarded and confined to a purely technical aspect, is regaining its rightful place: a pivotal subject at the crossroads of European Union law and international trade law, with multiple and sometimes unexpected implications and challenges (geopolitics, human rights, separation of powers, etc.).
“ We are rediscovering that customs law is not just about goods. It’s also about geopolitics. When we impose barriers or sanctions, we can, for example, deprive populations of access to certain goods, ” explains Marie. “ From within the European Union, we tended to forget this, but at the time of Brexit, many operators rediscovered, and quite abruptly, that borders do exist! ”
For Marie, these announcements are part of a much broader context: " We are witnessing a complete overhaul of the international trading system ," she observes. " The principles of the WTO, the most-favored-nation clause, are being challenged. We are returning to the law of the strongest, but clearly, states are accepting it. "
And recent decisions by American courts only reinforce this view. They have indeed ruled that the imposition of certain tariffs is unconstitutional because it falls outside the purview of the executive branch.
But, for Marie, this uncertain period nevertheless has its advantages.
These measures will notably lead companies to rethink their practices and to place customs issues at the center of the structuring of their international commercial operations and the negotiation of their contracts.
While Trump's announcements are erratic to say the least, " even American customs officials are struggling to keep up with the rule changes as announcements are not always followed by concrete implementations, " notes Marie.
She adds that their unpredictable nature, which would allow for invoking a case of force majeure, is not certain, because customs issues had already been a subject of his previous term and Trump had made it one of his main subjects during his last presidential race.
As is often the case when instability reigns, we return to the basics, and it is therefore contractual technique that can now come to the aid of companies to limit, or attempt to limit, the consequences of these upheavals.
And you, do you know what your contract says about customs duties?
Question of the month
Excessive formalism in civil procedure: for or against in concreto review?
According to the ECHR, excessive formalism can infringe the right of access to a judge guaranteed by Article 6§1, which must be concrete and effective: intended to serve the goals of legal certainty and good administration of justice, formalism must not become a barrier that prevents the litigant from having their dispute decided on its merits.
The rule is clearly stated.
But how should French judges ensure compliance when a procedural requirement is alleged to have been violated? Should they simply consider whether the French rule, taken in the abstract, independently of a specific case, is excessively formalistic (abstract review)? Or should they go further and consider whether the procedural rule, even if justified in itself, should nevertheless be disregarded in the case before them, in light of the concrete result of its application in the particular circumstances of the case (concrete review)?
Example of in concreto control: the judgment of the Court of Cassation of May 23, 2024.
In this case, concerning a procedure for the immediate return of a child following his unlawful removal, an appeals court had ruled that the mother's appeal declaration, not having been served on the public prosecutor, was invalid under Article 905-1 of the Code of Civil Procedure.

The Court of Cassation censured the decision, ruling that the Court of Appeal had been excessively formalistic in applying this rule, given that it had noted that the prosecutor had submitted his arguments before it and that the notice of appeal had been served on the father.
The rule applied by the Court of Appeal is therefore not condemned for its own sake but dismissed because of the concrete result of its application to the case at hand.
The in concreto control method is divisive.
For some, by varying the authority of formal rules according to the circumstances, this control jeopardizes the essential imperatives of legal certainty, predictability and equality of litigants.
For others, it represents a welcome safety valve, conducive to a reasoned and measured application of procedural rules. It can also be seen as an echo of the rule requiring a specific complaint in cases of procedural defects.
Avo-plumes! The debate is open.
Our Secondants in the news
Aurore Sauviat
Another month where you couldn't miss Aurore if you're interested in law and AI!
First, Aurore moderated the panel " Data Sovereignty in the Music Industry " composed of Gérald Olivon, Head of Production of bSHARP, Sébastien Tonglet , co-founder of Weezevent and Oliver Abitbol , co-founder of DELIGHT, during the Innovation & Tech Day at the Maison de la Radio et de la Musique on June 17.
The discussion focused on leveraging data for companies in the music industry.
Aurore then spoke on June 18, alongside Alizée Elbouby, at the conference organized by ANIA (National Association of Artificial Intelligence) on the unregulated adoption of AI by employees in companies.
The two lawyers explored the topic of the silent adoption of AI by employees, the potential risks for companies and, above all, the solutions to deal with it effectively.
Finally, you can find it here. His latest monthly column in Les Heures Claires magazine! This month: Images in the style of "Studio Ghibli": is a style legally protectable?
Bérénice Bauduin
We begin with his commentary on the decision of the Council of State of April 4, 2025 (474714) published in issue 2144 of the Semaine sociale Lamy of June 23, 2025.
Bérénice questions the possibility for a newly formed employers' federation, resulting from the restructuring of pre-existing organizations, to immediately assert its representativeness. She particularly emphasizes the complex web of regulations, not all of which may be suited to the realities of union activity.
On June 3, Bérénice traveled to Martinique where she presented the latest developments in QPC litigation to the Fort-de-France Court of Appeal as part of the ENM's continuing education program.
Finally, Bérénice has just taken over, with Baptiste Delmas, the Master 2 Social Law Jurists program at Paris 1. The duo took the opportunity to revamp this diploma which has already existed for more than 20 years.
The aim of this Master's program is to enable professionals already employed or undergoing career transition to acquire in-depth expertise in employment law. The degree covers both the challenges of individual and collective labor relations, as well as issues related to remuneration, social protection, and collective bargaining.
Designed for working professionals, this program is delivered by a top-level teaching team, composed of academics, judges, specialist lawyers, legal directors, HR managers and experts from public institutions such as the Defender of Rights, the Constitutional Council and the Directorate General of Labour.
A film, an exhibition, a restaurant…
For once, we're taking a break from the law to present this one-man show, somewhere between a TED Talk and a comedy show.
Sensitive souls beware...Daniel Sloss delivers a show of great mastery and perfect humor to address a serious and more relevant than ever theme: violence against women.
While the Scottish comedian had already accustomed us to investing serious subjects with talent, laughter and precision in his first two shows available on Netflix (Dark and Jigsaw), Daniel Slow definitely takes a step forward with X.
Behind his cherubic face (or perhaps that of a repentant Macaulay Culkin), Daniel Sloss begins his one-man show by stringing together deceptively innocent jokes to catch the audience off guard. Using an example drawn from his own experience, the comedian successfully creates discomfort by alternating between direct address to the audience, where laughter is no longer appropriate, and witty remarks that are as funny as they are clever.
And when we wonder how he will land on his feet, Daniel Sloss closes his 1 hour 30 minutes with a hilarious childhood anecdote that is above all symptomatic of the consequences of the absence of sex education classes.
His commitment does not end with the curtain rising, since, although the show is accessible for free on his website (you simply need to create an account to watch it), a note from the actor encourages you to make a donation to an association fighting against sexual assault.
The only downside is that the show is only in English with the option to insert subtitles...in English.
Thank you for reading.
That's all you need to know for this month, see you next month!
