...Law the world over. In subjects which follow the common law tradition, expect the increase in volume of cases to be studied. The "I have a say" to animate "case law arises when new decisions are made by judges in courts," is no accident. The word "jurisdiction" came from the latin words "juris" meaning "law", and "dico" meaning "I speak," which roughly translates to "I speak the law." Indeed, only judges or courts which has jurisdiction can validly make decisions or case law, true enough that they have a say. Side note: Learn to write the least but say the most. And learn how to give music to your words (at least in the reader's mind, while they read your piece). ============================ Introduction to Law Series Part 5 - Final Note Here, is a modern take on the our topic on the development of the Concept of Law overtime. Remember that our Political/Constitutional Law is based from that of the United States, and all our statutes are based on that (1987) Constitution. Notice the wordings of our Bill of Rights, you will find the similarities. Ex. No law impairing the obligation of contracts shall be passed. (Section 10 of Article III of the 1987 Philippine Constitution) Question: This is the "Freedom of Contracts," and is it a right created by the 1987 Constitution or is it a right that PREDATES the 1987 Constitution? No laws (no statutes) shall be passed which will impair the freedom of contracts. It never said, in anyway, that from this provision,......

...xxxxxx 05/20/2010 COM/220 Karen Moninger The life of a seven-year old girl tragically ends at the hands of a young boy. The court convicted Lionel Tate of first degree murder for beating the 48-pound girl, and sentenced him to life in prison. This punishment was a rather harsh judgment many in the community argue against today. Instead of incarcerating him for life, what other options are available? As teen violence continues to plague the nation, many people wonder if rehabilitation is an effective method for deterring future occurrences. Twelve-year old Lionel Tate took the life of a young girl named Tiffany Eunick. Lionel’s mother, a Florida Highway Patrol officer, was sleeping upstairs though she was responsible for babysitting Tiffany. The mother left the children watching television and playing together downstairs unattended. During horse play, Lionel begins to re-enact moves he saw watching wrestling. The 160-pound boy was responsible for cuts, bruises, fractured skull, lacerated liver, broken ribs and internal hemorrhaging on young Tiffany Eunick. Certainly the parents of the deceased child will want to see justice served for the loss of their loved one. Stories surface daily about a teen committing some sort of crime. A heart wrenching reality that many people will either themselves face, or know someone who has or will experience. The epidemic of teen violence is rapidly increasing; Statistics say youth under the age of 18 were arrested for......

Cjs/220 Final

...Assignment: Final Project: Appeals Process Paper Tony Thomas CJS/220 Jerri Mauldin August 21, 2011 An appeal is when a person who is convicted of a crime or is told they can’t do a certain thing and the person submits questions in writing why this decision was made and wants the verdict and the case to be looked at another time. Most causes for an appeal is from people thinking they are innocent or have the right to do what they want where they want to do it. The way an appeals process can affect the overall criminal procedures or process is if the appeal gets looked at and the ruling from the previous judgment gets overturned. The reason the system is affected is it can set an innocent man free or let whoever continue on doing what they want to do. If someone is put in jail or prison for a crime they didn’t commit and they send up an appeal and it gets the ruling reversed it can mean that the case would be reopened because the person who actually committed the crime is still on the loose. It also interrupts the process of the system because everything that has been put in writing saying that this person was guilty has now got to be withdrawn from record. It also means that the person who is behind bars goes free. A good way to improve the appeals process is not letting them sit so long before being looked at. This is a big problem in some states and needs to be corrected. Even though forensic science has brought a lot of people to the surface that we......

If Party Plates want their services readily available, convenient to their customers, and to remain productive; then they may consider the use of wireless devices to compete with other businesses that supply the same services. Mobile services allow Party Plates as well as their customers to access information real-time while connecting from mobile devices and other computing environments. Whether Party Plates use mobile devices or remain in its current position, we are recommending mobile computing and mobile commerce as wireless services to move Party Plates into the future. The pros and cons of each service are listed within this proposal. Mobile computing refers to real-time wireless connection between a mobile device and other computing environments, such as the Internet.

...Facebook, Friend or Foe What impact does Facebook have on our relationships? Patricia Fleming Com /220 March 28, 2012 Matt Turner “It has become appallingly obvious that our technology has exceeded our humanity.” – Albert Einstein Because of their growth and popularity social networking sites have in many ways, become a cultural phenomenal that has inched their ways into every facet of our lives, threatening to change the way in which we communicate both on and off line. If you are not convinced, take a look at what is going on the next time you visit your favorite restaurant. Look around at the other patrons; chances are the majority of them have a cell phone or some sort of mobile device lying next to their dinner plates. Instead of engaging in meaningful dialogue, they are sitting in a trance awaiting some sort of notification, tagging themselves in photographs, or “checking in” at the very restaurant you are sitting in; all the while socially “checking out”. Gone are conversations that used to contain the familiar catch phrase “how was your day?”, now if someone wants to know how a person’s day has gone, all they have to do is log onto Facebook and read about it. If that is not enough, consider some of the new words being added to our dictionaries. According to The Huffington Post (2011), words like “sexting”, “retweet”, and “cyberbully” have been added to the Concise Oxford English Dictionary, these words; which......
