French term (edited): Les cas de force majeure sont réservés.

'Cases of ... are not affected' is the UK notarial turn of phrase I had learned.

Note that force majeure, such as an industrial strike, does not aways square with an Act of God.

Here's a link showing that in EN we say "force majeure events" (or events of force majeure), rather than (as in FR) "cases of force majeure":

As Andres-Larsen explained in his reference, "Force majeure clauses, common in most commercial lease agreements, generally excuse, or temporarily delay, certain landlord or tenant lease obligations due to unforeseen circumstances beyond the parties’ control."

So in this context, where Heather has explained that the tenant/lessee is required to "achieve a target minimum turnover in order to continue to hold the lease or else the lessor can terminate it," the force majeure clause means that the tenant's obligation to achieve that target is excused if the reason they didn't achieve it was an event of force majeure.

It seems to be a case in which a proprietor or landlord needs to evict a tenant. In the unlikely event where a landlord has a need to evict a tenant from his or her abode, the landlord has the right to forcibly remove a tenant. That's only possible if an evicted tenant refuses to leave his or her abode. However, cases of forcible eviction are avoidable. It can only occur without prior notice if a tenant is found guilty of a serious offense. Otherwise, if a tenant fails to pay his or her rent then a landlord can begin an eviction process with a prior notice period of three (3) months. In another possible case, a landlord could need to evict a tenant for his or her own financial reasons. If so the landlord should allow the tenant a notice period of at least four (4) weeks.
However, cases of eviction are usually avoidable, as no one wants forcible eviction to occur.

(FR: Ce semble d'être un cas d'une éviction d'un locataire par un propriétaire. Au cas improbable où un propriétaire a besoin d'expulser un locataire de son lieu de résidence, le propriétaire a le droit de forcer l'expulsion du locataire seulement si le locataire refuse de partir de son lieu de résidence. Le propriétaire a le droit de forcer une éviction sans un période de temps de préavis seulement si le locataire s'est commis dans une grosse infraction. D'autrement si un propriétaire doit expulser son locataire, le deuxième n'a pas payé son louement pendant quelque temps; au cas duquel le propriétaire devrait commencer à faire l'éviction avec un préavis de trois (3) mois. Des autres cas sont possibles si un propriétaire doit cesser de louer son appartement pour ses motifs propres selon sa condition financière; au cas duquel il devrait commencer un procès d'éviction avec un période de temps de préavis de quatre (4) semaines. Cependant, on crois que l'expulsion forcée est évitable toujours.)

An event of unforeseen circumstances would need to be clearly and credibly explained. Similarly, if a tenant moves away from his or her address he or she should inform the landlord at least four weeks in advance.

In law, 'force majeure' constitutes unforeseeable circumstances that prevent someone from fulfilling terms of contract.
Unforeseen circumstances could even be extreme weather conditions, such as flood or an act of God.
It's also an irresistible compulsion or any superior strength.

Scottish Secure Tenancy Agreement
6. Ending the Tenancy
The tenancy agreement can be ended in any of the following ways:
6.1 By Notice
The tenant, together with any joint tenant, give the landlord at least 28 days written notice. The tenant must tell the landlord, at the same time, if married, or living in the property with another person at the same address, as husband and wife. If so, agreement from the partner or joint tenant is also required.
6.2 By written agreement
By written agreement between the tenant and any joint tenant and the landlord. The tenant must inform the landlord if married or living at the same address as husband and wife. Partner agreement may also be required.
6.3 By court order
The Sheriff grants an order for eviction following a request from the landlord. The tenant has a right to defend any legal action taken by the landlord against the tenant. Others living at the same address also have the right to be represented. The landlord may ask for such an order under Section 14 of the Housing Scotland Act 2001, on any of the grounds contained within Section 2 of the Act. Before doing so, the landlord sends a written warning. The landlord also includes written warning to any others known to bide at the same address, who are over the age of 16.
The following is a summary of the grounds contained within the Act, and does not change the legal position contained in that Act.
the tenant owes rent money or has broken some other condition of agreement, the tenant, someone residing at the same address, or anyone visiting the address, has been convicted of using the home or allowing it to be used for illegal or immoral purposes or a criminal offence punishable by imprisonment, which was committed in the house or the locality.
- The condition of the house or the common parts or furniture supplied has deteriorated due to the tenant's fault or because of a subtenant
- if the tenancy has been granted as a result of false information
the tenant, someone visiting the address, or anyone visiting it, has been anti-social to anyone else in the locality and it's not reasonable to transfer to tenancy to another address.
In the above cases the sheriff must also be satisfied that it is reasonable to make an order for eviction.
- the tenant, or someone residing at the tenant's address has been guilty of harassment, nuisance or annoyance in the neighbourhood or in the house, or has pursued a course of conduct amounting to harassment of someone else in the locality, and it's appropriate to transfer to another address.
Evidence of overcrowding, future plans to demolish property or carry out substantial work, or if the house is required by someone else with additional needs for adaptation, or if the lease from another proprietor has ended or will terminate within 6 months.
In the above cases the sheriff must grant an order for eviction if the tenant is offered suitable alternative accommodation as defined by Section 2 (part 2) of the Housing Scotland Act 2001. The Sheriff must also be satisfied that it's reasonable to grant the order.
6.4 By abandonment by the Tenant
If the address is found abandoned, the landlord sends a 4 week written notice to the address, as the landlord may forcibly enter the property to make it secure and change its lock. In the event of repossession of an address, a 6 month notice period should be applied. Safe custody and secure delivery of any property and / or belongings residing at the address is temporary before arrangements can be made to dispose of belongings. This conforms to requirements of regulations made by Scottish Ministers.
