Forests, as a component of the natural environment, are a common good that requires proper protection, both because of their utility values and because of the need to preserve their value in a condition that is at least not deteriorated for future generations. One of the manifestations of forest land protection is limiting the change of their use for non-agricultural and non-forest purposes, resulting from the Act of 3 February 1995 on the protection of agricultural and forest land, and also ratio legis of the Act of 28 September 1991 on forests. The purpose of this publication is to answer the question whether there is a rule in Polish law that explicitly excludes the development of forest land, or whether the legislator provides the right to develop forest land, and if so – what restrictions it is subject to and, consequently, what buildings that fulfil a residential function can be founded on forest land. The descriptive, historical and axiological methods were chosen as the research method. The considerations began with explaining the assumptions of forest land protection. In the further part of the publication, the concept of forest land and forest was interpreted. The proper part of the analysis discusses legal regulations relating to the construction of residential buildings on forest land that meet the needs of forest management, enriching them with comments resulting from the practice of implementing investment processes. The publication ends with final conclusions constituting a set of guidelines for the authorities applying the law when issuing decisions regarding the construction of residential buildings on forest land.

Termination or expiration of the real estate lease agreement for a photovoltaic farm results in the losing by the lessee the right to use the leased land and collect benefits from it. The terminated legal relationship of lease gives rise to the lessee's obligation to return the item, which should take place either in the condition specified by the parties in the concluded lease agreement or pursuant to Art. 705 of the Civil Code. The obligation to return the real estate is accompanied by a number of factual and legal activities performed by the lessee. Depending on their scope, the return obligation may aim to restore the land to its previous condition, including broadly understood land recultivation and restoration of its previous purpose, or limit the scope of the lessee's activities to restoring the original condition, taking into account, however, the wear and tear of the property resulting from the location of a photovoltaic farm on it and using the land in accordance with the concluded contract. The aim of the article is to consider the obligation to return real estate in terms of entities obliged to implement it, the deadline and the scope of its implementation.

The aim of the article is to evaluate the legal solutions adopted in the Act of 13 February 2020 amending the Construction Law and some other acts in the field of legalization of unauthorized construction. The cited Act is another example of the legislator's activities aimed at reducing the number of illegal constructions in Poland. Contrary to the regulations which is currently in force, the Act creates a single, clear legalization procedure, introducing, at the same time, unknown construction law, simplified procedure for legalization the so-called old illegal constructions. Legalization is still a phenomenon negatively assessed by the legislature, combined with the obligation to pay the legalization fee. The Act lacks solutions improving the detection of illegal constructions and the execution of demolition orders. Justified juridical doubts, in the aspect of compliance with the principle of equality before the law, are also caused by the formulation of provisions devoted to the legalization of illegal constructions, in which 20 years have passed at least since the construction was completed.
