Effective states do not expropriate, they propose. A concession reaches its midpoint, the administration suggests an extension in exchange for a doubled production share, the discussion is cordial, no threat is uttered, and the investor signs. There is no decree, no seizure, no breach: there is an amendment bearing its signature. When it later notifies the shortfall, its insurer produces against it the strongest document a file can contain against the party that created it, namely its own written consent.
The difficulty is not legal to begin with, it is one of perception. An investor that negotiates does not experience itself as a victim: it compares a bad deal with a worse one, obtains a few concessions, keeps its asset and its staff, and goes home having saved what could be saved. Only a year later, looking at the accounts, does it measure what the renegotiation transferred. By then everything that would have established the constraint has gone, because nobody builds a duress file while negotiating in good faith.
The law nonetheless knows the situation and handles it under the name of economic duress, or coercion depending on the system. Two conditions recur everywhere. There must be an illegitimate threat, and the party making it must have obtained a manifestly excessive advantage. The second is shown by figures and raises no particular difficulty here. The first is the wall, and it must be faced squarely: a state threatening to exercise a power it lawfully holds, refusing a discretionary renewal, tightening a standard, makes no illegitimate threat in the ordinary sense of the term.
Three configurations clear that wall, and a professional must recognise them because they are the only ones that carry. The first is the threat of an act the state could not lawfully perform, cancellation of a title on no provided ground, retroactive withdrawal, criminal proceedings without basis. The second is disproportion such that it deprives the operation of its substance, which returns to the creeping expropriation reasoning applied not to measures but to contractual terms. The third is simultaneity: an inspection campaign, a suspension of an ancillary permit, a tax audit opened during the negotiation, which say nothing separately and say everything together.
That last one is the most frequent and the worst exploited, because it requires treating the chronology as evidence. An import permit that stops being renewed in March, an environmental inspection in April, a transfer application left unanswered in May, a renegotiation proposal in June: none of those acts is illegitimate taken alone, and their alignment in time establishes the pressure far better than any witness. That chronology cannot be reconstructed afterwards; it is kept during, in a file nobody wants to open while the discussion is still going well.
Then comes the decision that makes the whole module, and it is taken before signing: what to do when the alternative is losing the asset? Refusing on principle is bad advice, because insurance does not replace an operation that continues. Signing and saying nothing is worse, because the signature becomes the opposing exhibit. The only conduct preserving both branches is to sign under express reservation, in the amendment itself where it can be got in, and otherwise in a contemporaneous letter addressed to the administration and to the insurer, stating that the agreement is made to preserve the operation and without waiver of rights arising from the circumstances that preceded it.
Something must be added about the insurer's position during that phase, because an insured rarely understands it. The insurer greatly prefers its insured to sign: a preserved asset and reduced returns cost it infinitely less than a total expropriation. It nonetheless has no interest in writing that down, and it will keep the ability to argue later that the signature was voluntary. The request to make of it is therefore precise and must be in writing: notify the circumstances before signing, set out the alternative, and ask for its position. Silence in reply is worth much, agreement is worth more, and never having asked counts against the insured.
What must be retained lies in a shift of timetable. This file is not won at the moment of the claim, where nothing remains but a signature and recollections, but in the four months preceding it, where it is enough to date what is happening and write two letters. It is the module where competence consists least in knowing how to argue and most in recognising, early, that a cordial negotiation is turning into a loss.
A European group has operated a bauxite concession in a West African country since 2014, under a title running to 2034 providing for a 6 per cent production royalty. In January 2026 the mines ministry proposes an extension to 2044 in exchange for a royalty raised to 12 per cent and a free 15 per cent state participation in the operating company's capital. No threat is uttered and no letter mentions any alternative. The group also notes that its import permit for reagents has not been renewed since November 2025, that an unannounced environmental inspection took place in December, and that two dividend transfer applications filed in October have gone unanswered. It signs the amendment in March 2026. In 2027 it notifies a loss to its insurer. What was its position worth, and what is it worth now?
Its position in January 2026 was far better than it is in 2027, and the whole gap lies in what it did not write down. Take first what remained usable. The three facts preceding the proposal are not illegitimate taken alone: an import permit may go unrenewed, an inspection may be unannounced, a transfer application may be slow. Their alignment across five months, immediately before a renegotiation proposal doubling the royalty and transferring fifteen per cent of the capital, is on the other hand exactly the configuration of simultaneity that establishes pressure without any threat having been uttered. That was its file, and it existed before it signed. Disproportion is likewise documentable: a royalty moving from six to twelve per cent together with a free participation can be costed, and the figure speaks. What was lost in March is decisive. By signing without reservation it produced the document saying it consented, and it produced it itself. The insurer will argue that the amendment is a voluntary act, that a twenty year extension is real consideration, and that nothing in the file establishes that a refusal would have led to the loss of the asset. Those three arguments are serious and the third is the hardest, because the alternative was never articulated by anyone. What remains to be done is modest and worth doing. Assemble the documentary chronology of the five months, with filing dates, acknowledgements and inspection reports, which still exist. Search the internal exchanges of the time for traces of what management thought the alternative was, a committee minute, a board note, a message saying what a refusal was worth. And find out whether other operators in the country received the same proposal and on what basis, which would distinguish a general policy from individual pressure and would cut one way or the other. The lesson to carry to the group's other assets is worth more than this file: four months earlier, two letters, one to the administration and one to the insurer, would have preserved the whole position.
- 01An effective state does not take, it proposes: there is no decree and no breach, only an amendment bearing the insured's signature, which becomes the opposing exhibit.
- 02Economic duress requires an illegitimate threat, yet a state threatening to exercise a power it lawfully holds makes none: that is the wall of the file.
- 03Three configurations clear it: the threat of an act the state could not perform, disproportion that empties the operation, and the simultaneity of measures that are innocuous separately.
- 04Refusing on principle is bad advice and signing in silence is worse: one signs under express reservation, in the amendment or in a contemporaneous letter to the administration and the insurer.
- 05The insurer prefers the insured to sign and has no interest in writing that down: ask for its position IN WRITING before signing, silence already being worth much.
