Judicial review allows courts to examine agency decisions and provide remedies if a person believes they have been injured by an agency. Before seeking judicial review, one must complete all agency appeal processes. Judicial review is not automatic and standards govern access to it. Courts can review agencies by statutes that create the agency or establish judicial review. Several barriers like no provision for review or preclusion of review exist. Procedures like standing, ripeness, exhaustion of remedies, and primary jurisdiction must also be followed to seek judicial review. The scope of review is limited but exceptions exist like reviewing issues de novo rather than just the agency record.
An administrative agency hearing is a proceeding where the agency investigates facts and enforces liabilities under existing laws. It is similar to a civil or criminal trial, with procedures set by agency statutes and administrative procedure acts. Hearings are typically held after other dispute resolution processes are exhausted or a claimant alleges a rights violation. While agencies have discretion over hearing procedures, courts require notice, a hearing, and findings to support decisions. Key hearing stages include pre-hearing procedures, presentation of evidence, findings, and a written decision stating the legal or factual basis.
Majority of agency decisions are informal and made through discretion. Claims for governmental benefits or services are initiated by clients through applications for licenses, claims, or employer arbitrations. Licenses are permissions granted by agencies and have standards in rules for issuance. Claims seek to restore rights or supply relief. Arbitration involves a third party decision while mediation aims to help disputing parties voluntarily agree. Settlements during hearings can resolve disputes without appeals. Advisory opinions clarify rules for the public or specific businesses. Courts give deference to agency procedures but ensure fair hearings without bias.
Chapter 6.investigations and information planningAPSU
Investigations are processes agencies use to gather information to assist with decision making. Agencies must collect information reasonably and in the public interest, and individuals have some protections for privileged information. While agencies have powers to demand records and conduct inspections, the 4th and 5th Amendments provide some protections for private information. Agencies can use procedures like search warrants, subpoenas, and grants of immunity to compel information gathering within legal limits.
The document discusses agency rules and regulations. It explains that rules are established by agencies to implement enabling statutes and solve problems of public concern. There are different types of rulemaking procedures, including informal which allows public comments, and formal which involves evidentiary hearings. Rules implement legislative goals and are directed towards the future, while decisions resolve specific disputes. The requirements for federal and state rulemaking are outlined.
The chapter discusses client rights when dealing with government agencies. It explains that clients have due process protections under the 5th and 14th Amendments in agency actions. Specifically, agencies must provide notice of hearings to clients, including details of charges and time and place of hearings, and clients have the right to be heard and receive a fair decision. The chapter also discusses how sovereign immunity protects some agency actions and personnel from legal claims.
Agency discretion refers to the power of administrative agencies to make choices among different policy options when applying laws to individual cases. Some level of discretion is necessary because laws may not address every situation. Safeguards against abuse of discretion include constitutional protections, statutes that define an agency's mission, and political and judicial oversight. Courts generally uphold an agency's discretion but will intervene if the agency's actions are deemed arbitrary, capricious or an abuse of power based on the circumstances of the case.
The document summarizes the development of administrative law in the United States from 1776 to present. It discusses key milestones like the creation of agencies like the Interstate Commerce Commission in 1887 and expansion of agency power during the New Deal. It also covers the delegation doctrine, which allows Congress to delegate legislative powers to agencies, and important court cases like Panama Refining Co. v. Ryan and A.L.A. Schechter Poultry Corp. v. United States that struck down unlimited delegations that lacked standards. The principles of separation of powers and federalism are also discussed in relation to administrative agencies.
Administrative law governs administrative agencies and defines their powers and legal limits. Agencies are created by legislatures to administer laws in areas requiring expertise like environmental protection. Administrative authority comes from enabling acts that define an agency's role and delegate powers from legislatures. There are different types of administrative laws including substantive laws protecting rights and procedural laws defining legal processes. Agencies have powers granted by their enabling statutes like setting standards, making rules and regulations, and deciding cases. Agencies can be regulatory, social welfare, independent, or executive depending on their functions and organization.
This document discusses the role of transportation in supply chain management. It makes three key points:
1. Transportation is a critical link in the supply chain that helps integrate supply chain activities and allows organizations to be more efficient. Effective transportation fosters improved supply chain integration.
2. Transportation bridges the gap between where goods are produced and where they are demanded, fulfilling a fundamental economic role. It also influences the location of economic activity and production facilities.
3. The concept of supply chain management has evolved over time from physical distribution to integrated logistics to the current focus on managing the entire extended enterprise and integrating transportation with product and information flows.
The document discusses key concepts in supply chain management. It outlines five major external forces driving change, including globalization and technology. It traces the evolution of supply chain management from physical distribution to integrated logistics management. Major issues facing supply chains are identified as networks and complexity, inventory deployment, technology challenges, transportation management, and security concerns. Efficient supply chains impact key financial metrics like cash flow, working capital, and return on investment.

The document discusses strategies for effective time management. It recommends making schedules and to-do lists, prioritizing tasks, scheduling downtime, and being flexible. It notes reasons for procrastination like perfectionism and provides strategies to overcome it like breaking large tasks into smaller parts. Other time traps to avoid are taking on too much and letting social time interfere. Scheduling allows planning to make the best use of time and avoid overcommitting. Suggestions include reviewing goals, eliminating unnecessary tasks, taking advantage of natural cycles, learning to say no, and rewarding effective time management.
This document summarizes findings from multiple studies that compared online, blended, and face-to-face learning environments. Some key findings include:
- Students in online conditions performed modestly better than those learning the same material through face-to-face instruction. Blended and purely online environments had similar learning outcomes.
- Asynchronous online instruction was found to be superior to synchronous instruction. Advantages were also found for online assessments and writing assignments.
- Instructor involvement was found to be a strong mediating factor for blended learning. Self-assessment questions also improved student learning.
The document discusses differences between digital natives and digital immigrants. Digital natives, who have grown up with technology their whole lives, process information differently than previous generations. They prefer graphics over text, multitasking, social networking and frequent rewards. This creates challenges for digital immigrant instructors whose teaching style does not align with how digital natives learn best.
