  • Electoral Reforms In India

    What is ‘Office of Profit’?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Office of Profit

    Mains level: Read the attached story

    Central idea: Jharkhand CM’s chair remains uncertain as the Election Commission (EC) is understood to have conveyed its decision in an office-of-profit complaint against him to the Governor.

    Why in news?

    • Under Section 9A of the Representation of the People Act, 1951, the CM could face disqualification for entering into a government contract.
    • The Constitution of India does not define the Office of Profit. It has only mentioned it under Article 102 (1) and Article 191 (1).

    What is ‘Office of Profit’?

    • In India, the concept of an “Office of Profit” refers to a situation where a person holds a government position that brings them financial gain or other advantages, while at the same time they hold an elected or other public office.
    • The idea behind this concept is to prevent any conflict of interest and ensure that elected representatives do not hold positions that may compromise their independence and impartiality.

    Indian context to this

    • MPs and MLAs, as members of the legislature, hold the government accountable for its work.
    • The essence of disqualification is if legislators hold an ‘office of profit’ under the government, they might be susceptible to government influence, and may not discharge their constitutional mandate fairly.
    • The intent is that there should be no conflict between the duties and interests of an elected member.
    • Hence, the office of profit law simply seeks to enforce a basic feature of the Constitution- the principle of separation of power between the legislature and the executive.

    What governs the term?

    • At present, the Parliament (Prevention of Disqualification) Act, 1959, bars an MP, MLA or an MLC from holding any office of profit under the central or state government unless it is exempted.
    • However, it does not clearly define what constitutes an office of profit.
    • Legislators can face disqualification for holding such positions, which bring them financial or other benefits.
    • Under the provisions of Article 102 (1) and Article 191 (1) of the Constitution, an MP or an MLA (or an MLC) is barred from holding any office of profit under the Central or State government.

    An undefined term

    • The officials of the law ministry are of the view that defining an office of profit could lead to the filing of a number of cases with the Election Commission and the courts.
    • Also, once the definition is changed, one will also have to amend various provisions in the Constitution including Article 102 (1) (a) and Article 109 (1) (a) that deal with the office of profit.
    • It will have an overarching effect on all the other sections of the Constitution.

    Factors constituting an ‘office of profit’

    • The 1959 law does not clearly define what constitutes an office of profit but the definition has evolved over the years with interpretations made in various court judgments.
    • An office of profit has been interpreted to be a position that brings to the office-holder some financial gain, or advantage, or benefit. The amount of such profit is immaterial.
    • In 1964, the Supreme Court ruled that the test for determining whether a person holds an office of profit is the test of appointment.

    What is the ‘test of appointment’?

    Several factors are considered in this determination including factors such as:

    1. whether the government is the appointing authority,
    2. whether the government has the power to terminate the appointment,
    3. whether the government determines the remuneration,
    4. what is the source of remuneration, and
    5. power that comes with the position

     

    Try this MCQ:

    Q. What is an “Office of Profit” in India?

    a) A position that is controlled by the government and comes with no financial gain or other benefits.

    b) A position that is controlled by the government and comes with some financial gain or other benefits.

    c) A position that is controlled by the private sector and comes with no financial gain or other benefits.

    d) A position that is controlled by the private sector and comes with some financial gain or other benefits.

    Why did Dr. Ambedkar resign?

    • Political differences with Nehru: He resigned as Law Minister, due to differences with the then PM, Jawaharlal Nehru, over the Hindu Code Bill. He specifically wanted to reform Hindu Personal Laws and not every personal laws in India.
    • Row over reforming Personal Laws: The bill aimed to reform Hindu personal laws related to marriage, divorce, and inheritance, but Dr. Ambedkar believed that it did not go far enough in granting women’s rights and wanted more radical changes.
    • Injustice to women: Ambedkar had proposed a more comprehensive set of reforms that would have given women greater rights in matters such as property ownership and inheritance, but his proposals were met with resistance from Nehru and other members of the government.

    Efforts to locate his resignation letter

    • The letter was not found in the National Archives of India and the Ministry of Home Affairs.
    • The Maharashtra government has also been unable to locate the letter in its archives.

    • Ambedkar’s resignation was a significant event in India’s political history and the reasons behind it are still relevant today.
    • The letter could shed light on the differences between the visionary Dr. Ambedkar and then mainstream politicians.

     

     

    India’s first Provisional Government (Constitutionally)

     

    • Jawaharlal Nehru became the first Prime Minister of India after the country gained independence in 1947.
    • The members of his first cabinet, which was sworn in on August 15, 1947, were as follows:
    1. Jawaharlal Nehru – Prime Minister and Minister of External Affairs
    2. Vallabhbhai Patel – Deputy Prime Minister and Minister of Home Affairs

    Scientists discover new ‘Quasicrystals’

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Quasicrystals

    Mains level: NA

    quasicrystals

    Scientists have discovered a new type of quasicrystal, one with 12-fold symmetry, in the Sand Hills of north central Nebraska, USA.

    What is a Quasicrystal?

    • Quasicrystal is essentially a crystal-like substance.
    • However, unlike a crystal, in which atoms are arranged in a repeating pattern, a quasicrystal consists of atoms that are arranged in a pattern that doesn’t repeat itself regularly.
    • For the longest time, physicists believed every crystalline arrangement of atoms must have a pattern that repeats itself perfectly over and over again.
    • However, this changed in 1982, when material scientist Dan Shechtman discovered crystal structures that are mathematically regular, but that do not repeat themselves.

    How are they formed?

    • Electrical discharge triggered quasicrystal formation in the recent finding.
    • It’s also the first time that researchers have found a quasicrystal somewhere other than meteorites or the debris from nuclear blasts.

    Applications of quasicrystals

    • There is no major commercial applications yet exploit properties of the quasicrystalline state directly.
    • Quasicrystals form in compounds noted for their high strength and light weight, suggesting potential applications in aerospace and other industries.
    • They can be used in surgical instruments, LED lights and non-stick frying pans.

    Agasthyarkoodam Observatory

    • The Agasthyarkoodam Observatory is an astronomical research observatory located in the state of Kerala.
    • The observatory is situated at an altitude of 1600 meters above sea level and is owned and operated by the Indian Institute of Astrophysics (IIA).
    • The observatory is equipped with a 1-meter optical telescope and various other instruments for studying the night sky.
    • The observatory is used for research and educational purposes and is open to the public for viewing night-sky objects.

    Why in news?

    • Agasthyarkoodam in the Western Ghats once housed a magnetic observatory that was established by Scottish meteorologist John Allan Broun.
    • Broun used it to record magnetic and meteorological observations in tandem with the Thiruvananthapuram astronomical observatory.
    • Broun’s astronomical research in India began after he was invited by the ruler of the erstwhile Travancore Uthram Tirunal Marthanda Varma to helm the Thiruvananthapuram observatory following the death of its first director John Caldecott in 1849.
    • The observatory started recording observations in July 1855.
    • However, it was closed in 1881 by the then Madras Governor Sir William Denison.

    What are magnetic observatories?

    • Magnetic observatories continuously measure and record Earth’s magnetic field at a number of locations.
    • In an observatory of this sort, magnetized needles with reflecting mirrors are suspended by quartz fibres.
    • Light beams reflected from the mirrors are imaged on a photographic negative mounted on a rotating drum.
    • Variations in the field cause corresponding deflections on the negative.
    • Their magnetograms are photographed on microfilm and submitted to world data centres, where they are available for scientific or practical use.

    From UPSC perspective, the following things are important:

    Prelims level: Solar Prominence

    Mains level: Not Much

    solar

    Recently, the sun puzzled many scientists with a large prominence near its north pole.

    What is Solar Prominence?

    • A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun’s surface.
    • Prominences are anchored to the Sun’s surface in the photosphere, and extend outwards into the Sun’s hot outer atmosphere, called the corona.
    • A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space.

    How are they formed?

    • Scientists are still researching how and why prominences are formed.
    • The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium.
    • The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo.
    • An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma.

    Today in History: Treaty of Alinagar

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Treaty of Alinagar

    Mains level: Not Much

    alinagar

    Signed on February 9, 1757, the Treaty of Alinagar between the Nawab of Bengal and the East India Company raised the curtains for British colonial expansion in India.

    Treaty of Alinagar, 1757

    • Signed on February 9, 1757, the Treaty of Alinagar was signed between Robert Clive of the East India Company and Mirza Muhammad Siraj Ud Daula, then Nawab of Bengal.
    • It is said to be one of the key events leading up to the Battle of Plassey later that year.
    • Plassey was where the English laid a significant blow, defeating the nawab. It paved the way for the East India Company’s takeover of Bengal.
    • The name Alinagar was a short-lived reference to modern-day Kolkata, and the treaty came about after the nawab was faced with both the British and Afghan forces.
    • He compromised with the former; however, the peace was short-lived.

    British advent in India: A quick backgrounder

    • After the Anglo-Mughal War which took place between 1686 and 1690, the British began consolidating their presence in the subcontinent.
    • It had established the Fort St. George in what was Madras, Fort William in then Calcutta and Bombay Castle by the beginning of the 18th century.
    • The British initially helped local princes and nawabs quell uprisings or revolts and they, in turn, gave them concessions.

    Course of the treaty

    • In January 1757, the British attacked the town of Hooghly, close to then Calcutta, with over 700 men.
    • The Nawab of Bengal, Siraj-ud-daulah, who had just come to power a year earlier in his early 20s, mobilised forces.
    • His troops would overpower the British and reach Calcutta on January 10, 1757, having lost over 600 men.
    • However, the losses sustained in the war had resulted in the nawab losing confidence.
    • He signed what came to be known as the Treaty of Alinagar with Robert Clive – who became the first British Governor of the Bengal Presidency – on February 9, 1757.
    • Siraj-ud-daulah agreed to the restoration of the company’s factories and allowed for the fortification of Calcutta.

    Aftermath of the battle

    • The British then moved on to wrest the remaining territories in Bengal from the French, laying siege to Chandannagar.
    • However, the move did not go down well with the nawab.
    • But, Daulah was also wary of Afghan forces under Ahmad Shah Durrani and the Marathas.
    • Traders in his kingdom were already wary of him and there was a conspiracy led by the likes of his military general, Mir Jafar.
    • Events would later culminate in the Battle of Plassey on June 23, 1757.
    • It resulted in the East India Company gaining hold of Bengal and was a significant event in its rise to power in the subcontinent.
