What are differences between the old and new constitution of Kenya?

Preamble: The preamble sets out the collective Kenyan spirit for making this constitution. Saves the spirit for posterity. The current or old constitution does not have a preamble. The spirit of our forefathers has been lost with the passage of time. Chapter1: The Draft recognizes the Sovereignty of the people and the supremacy of the constitution. This secures the people from abuse by those that will wield power. The current or old draft fails to recognize the supremacy of the people. Rather it places the institution of the Presidency above all else through direct and indirect interpretation. Chapt.2: The foundation of the Republic is set out. National values and principles of governance are the biggest win in this chapter. All institutions of public life as well as the officers populating them will be guided by these principles. This lays the foundation for similar interpretation of the law and standard behavior of public officers Does not exist in the current or old constitution. Chapt.3: Citizenship is defined. Citizen rights are explicit and secured. Dual citizens provided for thus protecting the Kenyans who may go to other countries so that they don't lose their Kenyan citizenship unless by personal choice. Women will confer citizenship to their spouses. National identity papers especially Passport is seen as a privilege. Women do not confer citizenship to spouses yet men easily do. Kenyans who emigrate to other countries lose their Kenyan status. Chapt.4.The Bill of Rights is for once so elaborate the state will not be allowed to grant rights. The exceptions as to when any right may be abrogated have been clearly provided for. Harassment and intimidation will be a thing of the past. Redress for breach of rights is provided for. Socio economic rights recognized. The Bill of Rights forms a basis for the realization of human dignity and self fulfillment. Chapter V of the current or old constitution provides for a minimalist Bill of rights. It recognizes rights which it quickly takes away. The government has historically implemented the law by the exceptions rather than the actual rights. Retrogressive. Chapt.5: Land and the environment are for the first time linked in the constitution. Land is now recognized as a common heritage. No one person may own obscenely large tracts of land. Foreigners cannot have absolute ownership of land. The classification of land protects the common heritage in the user systems in accordance with the National Land Policy. Absentee land lord phenomenon to go. The National Land commission will work within the national values and principles of leadership thus minimize abuse of power. Land is seen in the same way as any other property thus has been abused. No proper regulation has been in place. The commissioner of lands and the president have been the ones granting title thus abuse of the common heritage. Common resources and opportunities are shared equitably Chapt.6: For the first time our Constitution will have the principles of leadership and integrity. The chapter clearly outlaws unpatriotic conduct. Nepotism and tribalism will be dealt a serious blow. Anti corruption mechanisms are protected thus ensuring that corruption is meaningfully dealt with. Those in power will be bound by these principles hence favouritism will be significantly reduced if not out rightly finished. No provision exists. Weak anti corruption laws exist outside the constitution. Lack of political will to prosecute corrupt individuals has seen corruption grow tremendously. Leaders are guided more by the fact that they have power rather than exercise it responsibly. Chapt.7: The electoral system, the sanctity of the vote, the right of every adult citizen to participate either as voters or candidates, independent candidates, party lists to promote equity in representation are all gains that have been introduced. Inclusion of gender parity, constitutional regulation of political parties are all important gains so that the corruption that has hitherto existed with individuals owning political parties or parties being tribal/ ethnic outfits thus politically polarizing the country will be things of the past. The Independent Electoral and Boundaries commission will take away the gerrymandering that has previously occurred whereby government delineated boundaries to the benefit of some and to the disadvantage of others. In the current or old constitution, there electoral system is not elaborate. No gender equity. Political parties are fiefdom cases though recognized by the law just as vehicles for election. Electoral malpractices are not forbidden out rightly in the current one. Systems and structures promote nepotism. Chapt.8: The Legislature is clearly defined. The roles of both Houses provided for. The possibility of a rogue parliament is nibbed by the existence of the Senate. Procedures and matters of sovereign importance are provided for. The legislature is meaningfully separated from the executive. The calendar of the Houses controlled by law. Impeachment procedures secured from malicious political machinations. Provision for effective checks and balances between the President and the parliament are made. Other than the functions of parliament being provided for as being legislative, the separation of power is minimal. No real legal mechanism for checks and balances. No devolution so no upper house exists. The executive wields massive power and influence over the house thus causing plentiful of breaches without accountability. Chapt.9: The executive authority is DECLARED in the draft to derive from the people and must be exercised in accordance with the constitution. Therefore, executive authority must defer to the sovereignty of the people and respond to the national objects values and accountability mechanisms throughout the constitution. Deputy Presidency introduced. Deputy to seek election as a running mate. Appointment of public officers by the President is bound to be confirmed or authorized by parliament. Introduction of new procedures and known timelines for elections and the challenge if any to the presidential election in built in the draft. Election dates shall never again be a secret weapon nor will it be possible ever to swear presidents in surprise. Cabinet to be appointed from outside of parliament thus take away corrupt political practices. Number of cabinet positions set out. This will reduce unnecessary expense in servicing politically expedient objects. Possibility of abuse of power by the AG. Security of tenure for DPP which takes away the pos The current or old constitution vests all executive authority on the President (and in a limited way through the National Accord) with the Prime Minister. The executive authority is authoritarian and does account to the people other than in a very limited way to parliament which is itself not effectively independent or checked. Lacks clarity regarding the presidential election disputes resulting to legitimate disputes being obfuscated. The AG is executive, prosecutor, and Parliamentarian. His office both abuses power to prosecute and persecute. The DPP is subordinate to the AG thus making his/ her independence tenuous. Chapt.10: Judicial authority is declared to derive from the people. This is key because the judiciary must therefore serve the best public interest. An independent and better mixed Judicial Service Commission is established with Public participation. Judges to be vetted and approved by Parliament. The p[positions in the judiciary to be advertised and competitively filled taking into account the principles of equity, equality expertise. Office of Deputy Chief Justice to promote administrative accountability. The judiciary is just mentioned as an organ. Courts established but not guided by any people based principle. The law applicable doesn't derive authority from the sovereignty of the people. Judges appointed in opaque, manner with a JSC which is only beholden to the President. Neither standards set out nor criteria for appointment other than age. Corruption has been rampant without any checks and balance or accountability. Chief Justice has no deputy thus creating incentive for personal loyalty from individual judges to the CJ thus killing Judicial independence. Chapt.11: Devolution of power and resources has been provided for too promote effective citizen participation in governance and accountability. County governments seek to replicate national governance structures at the local level where taxation will be levied and supported so as to enhance development at local levels as well as provide equitable and more opportunities for citizens to participate meaningfully in matters of government. Does not contain any form of devolution. Decentralization only transfers the challenges of the central government plagued with corruption and nepotism. The current (old) constitution concentrates all power and authority on the president with little or no citizen participation other than the periodic ritualistic elections. Chapt.12: Imposition of tax, regulation of taxation, allocation and establishment of funds are key features of the draft. Distinct objects and purposes of taxes is clearly set out. Public loans to be approved by parliament as well as to be made public. The creation of budget and revenue commissions will strengthen accountability and reduce theft or misuse of public resources for the benefit of a few regions rather than the whole country. The current or old constitution creates the consolidated fund but gives parliament the power without capacity to supervise its application. There is no budget office. Only executive budgets, usually secretly thus providing the perfect environment for misappropriation of public resources. No known principles or guidelines for accountability and transparency. Public debt incurred by the executive and kept secret thus providing the best environment for corruption and theft. Chapt.13: The public service is established with principles of probity, best public interest, equality, equity, transparency and the national values. That public servants are employees of the public rather than their bosses is clearly set out. Regulation of the service provides for coherence between the national and country governments. Public service taken to serve at the pleasure of the president. Neither accountability nor principles. No safeguards against ethnicity and nepotism. Official secrecy and chain of command that does not respond to public accountability distorts service delivery. Chapt.14: National security is clarified and is founded on the national principles and values. National security is now subjected to parliamentary supervision and under authority of the constitution. The various commissions and services are periodically responsible to the people through parliament. The national security considered a secret. The president embodies national security. His personal interests are not distinguished from the collective national interest. Public officers do not distinguish between personal misadventures from real national security concerns thus precipitating abuse. Chapt.15. For the effective delivery of service and within the framework of constitutional accountability. Various commissions have been established so that they may safeguard the common national values in respect of their mandates. The commissions are protected from manipulation. Their substantive and operational independence assured. All commissions other than the Judicial Service Commission and the Public Service Commission are established subordinate to the constitution. Even these two are created in such a way as to serve the interests of the executive or just president. These commissions are used to perpetuate impropriety and nepotism rather than common public good. They are not independent and are manipulable as part of the public service. Chapt.16: The amendment of the constitution is made deliberately difficult and cumbersome so that the values espoused are not lost through frivolous or sectarian political interests depending on elections and circumstances. The foundational provisions will require referenda to cause amendment whereas the other amendments will require the absolute majority of the two houses. Citizens also reserve the right to petition for amendment through a rigorous but safe mechanism of raising one million signatures. The current or old constitution does not have any safeguards against parliamentary amendment. Indeed as a result the constitution changed its character from the innocuous one of 1963 to the mongrel and piece of dictatorship it is today. Parliament not accountable to the public in any way. The public have no constitutional mechanism for causing amendments other than depending on the goodwill of the politicians.


What is a neutral wire on a 240 wire?

Answer for USA, Canada and countries running a 60 Hz supply service.In countries running 60Hz services the electricity utility powerlines going to residential streets and roads are operated at nominal voltages going from 2400 up to 7,200 and even 14,400 volts relative to ground. To provide 240 volts to the buildings, pole transformers are used having step-down ratios going from 10-to-1 up to 60-to-1. For each 240 volt phase the pole transformer has a center-tap so that +120 volts can be supplied from the half-winding on one side of the center tap whenever -120 volts is being supplied from the other half-winding. (It is important to remember that in fact the voltages in the two half-windings or "legs" always alternate from +120 volts to zero to -120 volts 60 times per second.) The center point tap between the two "legs" - known as the "neutral" connection - is also a convenient point to make the safety grounding connection for the transformer.The actual measured voltage in your house branch circuits (to which its 120 volt receptacle outlets and lamps are connected) will normally be around 120 volts. However all lamps and appliances are rated for the maximum operating voltage (usually 120 volts and 240 volts), thus there is much confusion about the actual level of the supply voltages.However, all that was just a necessary preamble to the actual answer to this question! Here comes the answer:An appliance that is designed to be connected to strictly 240 volts 60 Hz is connected with only a two wire cable plus a safety ground wire. (For example 240 volt 60 Hz base board heaters use that.)Most big appliances such as air conditioners, dryers, some kitchen ranges, etc., which need to draw high power, are nowadays supplied not from a 120 volt "leg" but at a full 240 volts by connecting them to both of the legs, "+120" and "-120", which come from the pole transformer as was described above.However many of these appliances also need a 120 volt feed for such things as lamps, time-clocks, program control circuits, etc. To get that 120 volts they must use the neutral wire which comes from the center tap of the pole transformer.Thus an appliance designed to run on a 240/120 volt 60 Hz supply can have up to 4 wires altogether:two 120 volt 60 Hz live "hot legs" which run in opposing phase to one another: when one hot leg goes "+" (120 volts positive) the other leg goes "-" (120 volts negative);a neutral wired as a "central" common current return conductor:a safety "ground" wire but this is not required if the appliance is of the type known as "double insulated"..One of the two hot wires feeds a 120 volt alternating voltage from the power station to the 120 volt load - the clock or programmer - and, because the voltage is alternating, that load draws an alternating current. Then the neutral wire returns the current to the power station to complete the circuit.Different voltage levels are used in different countries around the world. The reason to use a higher voltage is that it is more economical: the current is less, so the wires can be smaller. On the other hand, the reason why lower voltages are still used in homes and offices for supplying small appliances, lighting, etc. is safety: "The lower the voltage, the safer it must be".Important Note:Do not confuse a Neutral with a Safety Ground (or Earth) connection.For more information on that topic please read the answer to the Related Question which is shown below as:"What is the purpose of the ground wire on an appliance or in a house branch circuit?"Answer for countries in Europe and other world areas running a 50 Hz supply service.In countries running 50Hz services the electricity utility powerlines going to residential streets and roads are typically operated at many thousands of volts. Pole or street-level sub-station transformers are used which have the necessary step-down ratio to provide 230 volts to the buildings. The "live" wire comes from one end of the transformer's secondary winding and the "neutral" wire comes from the other end, which is also a convenient point to make the safety grounding connection for the transformer. The split-phase type of service, as is commonly used for 60Hz systems, is not used for 50Hz systems because all appliances, lamps, socket outlets, etc. run at 230 volts.So a neutral wire is always needed as the return path back to the power station for any 230V 50Hz single-phase circuit in which only one live wire feeds alternating current into the connected load.Important Note:Do not confuse a Neutral with a Safety Ground (or Earth) connection.For more information on that topic please read the answer to the Related Question which is shown below as:"What is the purpose of the ground wire on an appliance or in a house branch circuit?"As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


Who taught Galileo galilei?

Galileo's father, Vencenzio, was a mathematician as well as a musician. He is the one who taught Galileo until the age of ten. After that, the family moved to Florence, where Galileo attended a monastery where he learned Latin and Greek. He also studied religion and music.
