KATYAL" Most people do not hold those who intentionallyflout property laws in par- ticularly high regard. The overridingly negative view of the property lawbreaker as a "wrongdoer" comports with the status of property rights within our charac- teristically individualist, capitalist, political culture. This reflexively dim view of property lawbreakers is also shared, to a large degree, by property theorists, many of whom regard property rights as a relatively fixed constellation of enti- tlements that collectively produce stability and efficiency through an orderly sys- tem of ownership. In this Article, Professors Peihalverand Katyal seek partially to rehabilitate the reviled characterof the intentional property lawbreaker, and to show how property outlaws have played an important role in the evolution and transfer of property entitlements.

  • Lomfeld 2017 Property
    Bertram Lomfeld A Political Grammar of Property Law Preliminary Draft 02/2017 DELIBERATING PROPERTY: A POLITICAL GRAMMAR OF PROPERTY LAW Bertram Lomfeld 1 Political Properties: What? Who? Why? 2 Justificatory Reasons for Property 3 A Bundle of Property Rights 4 A Bundle of Property Duties 5 Property As Deliberation 6 Applying the Grammar: Some Tentative Case Studies Some people understand property as a natural human right. Meant to depoliticize property it is perhaps one of the most political arguments one could take. This paper is starting from an opposite perspective, i.e. fundamental value pluralism. Starting from value pluralism, it is impossible to define a ‘universal’ core of property either on a conceptual or a normative (justificatory) level. To understand property as a clear ‘human right’ might still allow for a conceptual ‘structural’ pluralism, 1 but it accepts only private autonomy and subjective freedom as justificatory basis. For an economic perspective, the core function of property rights is the internalization of social cost.2 So, it all depends on the perspective: ‘How one defines the core of property depends on what values one thinks property serves‘.3 This paper attempts to sketch a more freestanding genuinely pluralistic property theory relying on a ‘deliberative’ discourse theory.4 The strategy of a ‘deliberative legal theory’ is pragmatic and idealistic at the same time.5 Considering law as a constitutive structure of social cooperation, it analyzes social practices of law and theory discourses (scholarship, legislation and judicial cases). It deconstructs or ‘liquefies’ monistic normative principles or policies and tries to reconstruct them as an integrative yet plural ‘political grammar’ for legal argumentation.

  • Scientist Letter to Senate on Natural Resources
    Dear Senator, We the undersigned signatories, leading researchers and practitioners from the various biological and earth science disciplines, are writing to urge the Senate to pass legislation that will reduce U.S. greenhouse gas emissions and begin to substantively address the impacts of climate change on our communities, wildlands and wildlife this year. The science is clear: we must both reduce greenhouse gas pollutants and safeguard wildlife and natural resources already impacted from climate change. The time to act is now. The increase in human-caused emissions is responsible for driving climatic changes worldwide, and negatively impacting both human and natural systems. Climate change is already causing serious damage and disruptions to wildlife and natural ecosystems, threatening the collapse of natural systems that cross ecological or biological thresholds. This collapse will result in the loss of the environmental goods and services they provide to society, as well as the loss of the biological diversity that sustains their production. The warming of rivers, streams, lakes and wetland, the changes in natural disturbance regimes and increased incidence of pest and disease outbreaks, and changes in the seasonal timing of both plant and animal life history events such as reproduction, migration, and species ranges are disrupting ecological communities. Profound changes such as the melting polar ice caps and glaciers, acidification of the oceans, rise in sea levels, and an increasing incidence of intensified storms, drought and catastrophic fires will stress natural systems and have devastating implications for people, our treasured landscapes and wildlife. Wildlife, natural resource and water managers will be increasingly challenged by species assemblages and climate-related stressors that have never previously occurred.

    Contracting the Right to Roam Wallace McNeish and Steve Olivier © 2017, Palgrave Macmillan, reproduced with permission of Palgrave Macmillan This extract is taken from the author's original manuscript and has not been edited. The definitive, published, version of record is available in the Palgrave Handbook of Leisure Theory, edited by K. Spracklen et al., available from: http://www.palgrave.com/gp/book/9781137564788 Contracting the Right to Roam Wallace McNeish and Steve Olivier Introduction This chapter critically examines the issue of free recreational access to the environment – the right to roam, from the perspective of political philosophy. We begin by setting the right to roam within a comparative socio-legal context that indicates how ongoing social and economic change has moved it to centre stage in the increasingly contested sphere of what Rojek (2001; 2010) calls leisure politics. We then move on to consider the political- philosophical debate that has traditionally revolved around rights and duties pertaining to private property, and the conception of the social contract. In recent decades the emergence of environmental ethics – and in particular conceptions of environmental sustainability and environmental justice, have added extra dimensions of complexity to the philosophical terrain upon which the right to roam is contested. Two very different versions of the social contract will be juxtaposed to bring the key arguments into high relief. On the one hand we consider Hardin’s influential eco-Hobbesian Tragedy of the Commons (2000, [1968]) thesis. This positions human beings as possessive, selfish and competitive individuals who will inevitably be responsible for generalized environmental degradation, unless their restless desires (including to roam) are held in check by a coercive Green Leviathan.

  • National Fish and Wildlife Foundation Draft Business Plan for the Path of the Pronghorn March 24, 2009
    National Fish and Wildlife Foundation Draft Business Plan for the Path of the Pronghorn March 24, 2009 NFWF Pronghorn Biz Plan.indd 1 8/12/09 11:29:01 AM What Is a Business Plan? A business plan serves two broad, primary functions. First, it provides specific information to those (e.g., prospective investors) not familiar with the proposed or existing business, including its goals and the management strategy and financial and other resources necessary to attain those goals. Second, a business plan provides internal guidance to those who are active in the operation of the business, allowing all individuals to understand where the business is headed and the means by which it will get there. The plan helps keep the business from drifting away from its goals and key actions through careful articulation of a strategy. In the context of the National Fish and Wildlife Foundation’s conservation efforts, business plans represent the strategies necessary to meet the conservation goals of Keystone and other initia- tives. Each business plan emphasizes the type(s) and magnitude of the benefits that will be realized through the initiative, the monetary costs involved, and the potential obstacles (risks) to achieving those gains. Each of the Foundation’s business plans has three core elements: Conservation Outcomes: A concrete description of the outcomes to which the Foundation and grantees will hold ourselves accountable. Implementation Plan with Strategic Priorities and Performance Measures: A description of the specific strategies that are needed to achieve our conservation outcome and the quantitative measures by which we will measure success and make it possible to adaptively revise strategies in the face of underperformance.

  • Natural Rights to Migration?
    Draft only (and a very baggy and messy one at that). Please do not cite or quote without permission. Natural Rights to Migration? Christopher Bertram Department of Philosophy, University of Bristol [email protected] INTRODUCTION It is often claimed that states enjoy, as a consequence of their sovereign sta- tus, the right to control the passage of outsiders through their territory and that they have a discretion to admit or to refuse to admit outsiders, whether those outsiders be tourists, business travelers, would-be economic migrants, or even refugees. Or, to be more exact, such limitations on that right to control are derived from the agreement of states to treaties and conventions, agree- ment which they could have withheld and could yet revoke. As a statement of the legal position this is not completely uncontroversial,1 but my aim in this paper is not to make a contribution to international law or law at all. Rather, my concern is with political philosophy and with the issue of whether 1See, for elaboration the discussion in Nafziger (1983). 1 2 any state, or state-like entity, could, in fact, have the moral right to exclude foreigners who wish to enter its territory. Whilst some people think it obvious that states have such rights to con- trol and limit movement, to others, this claim can seem utterly mysterious. Borders are not natural features of the world – though they may track such features – and the idea that some people have the right to declare an arbi- trary line and the right to forbid others from crossing it, and that those others have the moral duty to comply and not to cross without permission can seem simply bizarre.

    POVERTY, PROTEST AND SPORT: POACHING IN THE EAST MIDLANDS c.1820-c.1900 ROSEMARY MUGE, MA. Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy October 2017 Abstract In the East Midlands counties of Derbyshire, Leicestershire and Nottinghamshire levels of poaching equalled or exceeded those in many counties which are thought of as prime poaching areas. Using principally Criminal Registers, Game Laws Returns to Parliament, and local newspapers of the period, this study shows that people poached from three motives: because they were poor; because poaching was a sport; and as a protest. Day and night poachers, including night poaching gangs frequently involved in affrays, pursued their activities undeterred by the efforts at prevention of the landowners, police and courts. Poaching here was predominantly for ground game and declined in the last quarter of the century, but continued to be a source of anger and frustration for game preservers and the authorities to the end of the period. The poaching war in these counties, waged in an area with large aristocratic estates but where extreme game preservation was viewed critically, was not perceived as impacting on law and order in general. This was unlike Lancashire, where the activities of poachers were regarded as being a threat to the fabric of society. The causes of these differences between the East Midlands and Lancashire were rooted in police practice, attitudes to game preservation, and differences in gentry sport and hunting. (Total words in thesis: 90,313) Acknowledgements Having begun to study history twenty years ago and finally submitted this thesis in retirement, there are many people to whom I am beholden.

    June 12, 2015 Governor Steve Bullock Office of the Governor PO Box 200801 Helena MT 59620-0801 Superintendent Daniel Wenk Yellowstone National Park Yellowstone Bison Management Plan EIS PO Box 168 Yellowstone National Park, WY 82190 Dear Governor Steve Bullock and Superintendent Daniel Wenk, Buffalo Field Campaign is requesting the state of Montana and Yellowstone National Park evaluate managing wild buffalo like wild elk on public lands in Montana as an alternative in the Bison Management Plan. The Manage Wild Buffalo like Wild Elk in Montana alternative supports buffalo’s freedom to roam America’s public lands. The alternative would ensure wild buffalo are allowed to inhabit public lands and establish a population in Montana. Like wild elk, wild buffalo would be managed by hunting based on sustainable populations in available habitat in Montana. The habitat to sustain a wild buffalo population exists on public lands in Montana. What remains missing is a commitment by Montana's Governor to allow wild buffalo to inhabit National Forests and other public lands beyond Yellowstone National Park. As practiced by the state of Montana and Yellowstone National Park, adaptive management has been a dismal failure. Despite several changes to the plan, the framework continues to operate on faulty assumptions and outdated information. The public has roundly criticized adaptive management and an independent review by the U.S. Government Accountability Office found fundamental problems that persist to this day. We strongly encourage using the best available science to guide informed management decisions. The Manage Wild Buffalo like Wild Elk in Montana alternative meets the mandate from the U.S.

In the civil law system, there is a division between movable and immovable property. Movable property roughly corresponds to personal property, while immovable property corresponds to real estate or real property, and the associated rights and obligations thereon. The concept, idea or philosophy of property underlies all property law. In some jurisdictions, historically all property was owned by the monarch and it devolved through feudal land tenure or other feudal systems of loyalty and fealty.
