Evoking “Act of God”

The force majeure or “Act of God” clause has its origins in the Napoleonic Code.
The finance ministry had issued an office memorandum inviting attention to the force majeure clause (FMC) in the 2017 Manual for Procurement of Goods issued by the Department of Expenditure.
It clarified that the pandemic should be considered a case of natural calamity and FMC may be invoked, wherever considered appropriate.

What is a force majeure clause?

The law of contracts is built around a fundamental norm that the parties must perform the contract.
When a party fails to perform its part of the contract, the loss to the other party is made good.
However, the law carves out exceptions when the performance of the contract becomes impossible for the parties.
A force majeure clause is one such exception that releases the party of its obligations to an extent when events beyond their control take place and leave them unable to perform their part of the contract.
FMC is a clause that is present in most commercial contracts and is a carefully drafted legal arrangement in the event of a crisis.
When the clause is triggered, parties can decide to break from their obligations temporarily or permanently without necessarily breaching the contract.
Companies in such situations use the clause as a safe exit route, sometimes in opportunistic ways, without having to incur the penalty of breaching the contract.

What is Vitamin-D?
Vitamin D is an essential vitamin that has myriad positive effects on several systems in the body.
Unlike other vitamins, it functions like a hormone and every cell in your body has a receptor for it.
It is sparsely found in certain fatty fish and fortified dairy products, and it is extremely difficult to get the Recommended Daily Intake (RDI) of 600-800 IU from diet alone.
There are two main forms of vitamin D in the diet:

– Vitamin D2 (Ergocalciferol) — found in plant foods like mushrooms.
– Vitamin D3 (Cholecalciferol) — found in animal foods like salmon, cod and egg yolks.

Common signs and symptoms of the deficiency
Vitamin D deficiency is incredibly common and most people are unaware of it, as the symptoms are subtle and nonspecific.

– Getting sick or infected often with common cold and flu, because of a weak immune system.
– Fatigue and tiredness
– Bone and muscle pains
– Depression
– Impaired wound healing
– Bone loss and osteoporosis

Sources of Vit. D

Sunlight is the best natural source of vitamin D. Sunlight synthesizes cholesterol into Vitamin D3.
Usually, 20 to 30 minutes of sun exposure between 10 am and 3 pm is adequate to meet daily requirements, in places with minimum pollution levels.
